Versatile synthesis of 2 ‘-amino-2 ‘-deoxyuridine derivatives with a 2 ‘-amino group carrying linkers possessing a reactive terminal functionality

2,2′-Anhydrouridine has been successfully converted into the appropriate 2′-amino-2′-deoxyuridine derivatives in a reaction with isothiocyanates obtained from amino acids or alpha,omega-diaminoalkanes. The initially formed oxazolidine-2-thione ring is cleaved under basic conditions into the corresponding 2′-amino(substituted)-2′-deoxyuridine derivatives. The implemented additional terminal functionality in the substituent attached to the 2’-amino group allows further modifications with e.g., fluorophore moiety. (C) 2016 Elsevier Ltd.

Stereospecific Electrophilic Fluorocyclization of alpha,beta-Unsaturated Amides with Selectfluor

An efficient fluorocyclization of alpha,beta-unsaturated amides through a formal halocyclization process is developed. The reaction proceeds under transition-metal-free conditions and leads to the formation of fluorinated oxazolidine-2,4-diones with excellent regio- and diastereoselectivity. The evaluation of the reaction mechanism based on preliminary experiments and density functional theory calculations suggests that a synergetic syn-oxo-fluorination occurs and is followed by an anti-oxo substitution reaction. The reaction opens a new window in the field of stereospecific fluorofunctionalization.

Detailed investigations into the Akabori-Momotani reaction for the synthesis of amphetamine type stimulants: Part 2

The Akabori-Momotani reaction can be used to synthesise pseudoephedrine in 50% yield from N-methylalanine and benzaldehyde. This paper investigates electronic effects of substituted benzaldehydes on the reaction to synthesise amphetamine type stimulants and identifies several new Akabori-Momotani by-products, 1-[(4-methoxybenzyl)(methyl)amino]ethanol (11c), 2-(4-methoxyphenyl)-3,4-dimethyl-1,3-oxazolidine (12c), 1,2,3,4-tetramethyl-5,6-di-(4-methoxyphenyl)piperazine (13c) and 1,2,4,5-tetramethyl-3,6-di-(4-methoxyphenyl) piperazine (14c). This paper also investigates pseudoephedrine and methamphetamine isomeric distribution from the Akabori-Momotani reaction with the aid of molecular modelling to understand why more pseudoephedrine than ephedrine is produced.

Palladium-catalyzed three-component tandem cyclization of buta-2,3-dien-1-ol, aryl iodides, and imines: an efficient protocol for the synthesis of oxazolidine derivatives

An efficient three-component tandem cyclization reaction for the synthesis of highly substituted oxazolidines was achieved through the Pd-0-catalyzed cyclization of buta-2,3-dien-1-ol with aryl iodides and imines. A range of R-1 and R-2 functional groups is well-tolerated while affording cyclization products in moderate yields and with moderate to high diastereoselectivities.

When Light and Acid Play Tic-Tac-Toe with a Nine-State Molecular Switch

Combining different molecular switching functions in a single molecule is a simple strategy to develop commutable molecules featuring more than two commutation states. The present study reports on two molecular systems consisting of two indolino-oxazolidine (Box) moieties connected to an aromatic bridge (phenyl or bithiophene) by ethylenic junctions. Such systems, referenced as BiBox, are expected to show up multiaddressable and multiresponsive behaviors. On one hand, the oxazolidine ring opening/closure of Box moieties can be addressed by chemical stimuli, and on the other hand, the trans-to-cis isomerization of the ethylenic junctions is induced by visible light irradiation (with a thermal back conversion). NMR and UV-visible spectroscopies allowed to characterize up to nine out of the ten theoretically expected commutation states as well as to measure the kinetics of the interconversions. Also, steady state fluorescence spectroscopy measurements highlighted the strong influence of the open/closed states of the Box moieties on their emission properties.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 99395-88-7, in my other articles.

In the title compound, C19H18FNO3S, the five-membered oxazolidine ring adopts an envelope conformation with the methine C atom of the fused bond as the flap. Its mean plane is oriented at a dihedral angle of 50.38 (1)degrees with respect to the fluorophenyl ring. The six-membered thiopyran ring has a half-chair conformation and its mean plane is almost coplanar with the fused benzene ring, making a dihedral angle of 4.94 (10)degrees. The two aromatic rings are inclined to one another by 85.96 (11)degrees, and the mean planes of the oxazolidine and thiopyran rings are inclined to one another by 57.64 (12)degrees. In the crystal, molecules are linked by C-H center dot center dot center dot pi interactions, forming a three-dimensional structure.

Palladium(II)-Catalyzed Enantioselective Synthesis of alpha-(Trifluoromethyl)arylmethylamines

[GRAPHICS] Trifluoromethylacetaldimines, generated in situ from the corresponding N,O-acetals, undergo 1,2-addition of arylboroxines under palladium(II) catalysis to generate a variety of alpha-(trifluoromethyl)arylmethylamines with good to high enantioselectivity (up to 97% ee). The pyridine-oxazolidine (PyOX) class of ligands was found to be particularly suitable for this transformation, which proceeds without exclusion of ambient air and moisture.

2-Trifluoromethyl-2-methyl-4-phenyloxazolidine: A new chiral auxiliary for highly diastereoselective enolate alkylation

The alkylation reactions of an amide sodium enolate derived from a C-2 disubstituted trifluoromethylated oxazolidine (Fox) chiral auxiliary occurred in good yields with a very high diastereoselectivity (>98% de). Compared to the C-2 monosubstituted trifluoromethyl analogue, this chiral auxiliary is much more stable towards bases at temperature over -35 degrees C because the dehydrofluorination reaction is avoided. However asymmetric enolates quaternarization was not successfully achieved with this new chiral auxiliary. (C) 2011 Elsevier B.V. All rights reserved.

Diastereoselective construction of syn-alpha-oxyamines via three-component alpha-oxyaldehyde-dibenzylamine-alkyne coupling reaction: application in the synthesis of (+)-beta-conhydrine and its analogues

A Cu(I)-catalyzed alpha-oxyaldehyde-dibenzylamine-alkyne coupling reaction was delineated for the construction of alpha-oxyamines with excellent yields and diastereoselectivity. Crystal structure analysis and theoretical calculations were also supportive of the formation of syn-alpha-oxyamines as the major products. Application of the methodology addresses the synthesis of (+)-beta-conhydrine along with analogs having two different diversity features. A ring size variation allows construction of piperidine and pyrrolidine rings while a variation of side arm functionality is achieved by complete regioselective opening of epoxide by different organocopper ylides (Gilman reagents). A lactam-Cu(I) complexation motif is proposed which allows an intramolecular attack of ylides at the terminal epoxy carbon via the six-membered cyclic transition state. The present work features the synthesis of (+)-beta-conhydrine over eight steps in 26% yield and its seven analogs in 21-28% yields.
