Synthesis and characterization of different types of epoxide-based Mannich polyols from low-cost cashew nut shell liquid

Cashew nut shell liquid (CNSL) is a natural aromatic organic oil consisting of phenolic compounds with interesting structures. Extraction of CNSL was performed in a Soxhlet apparatus. The major (90 %) component of CNSL is anacardic acid, which is easily decarboxylated to cardanol (10 %) by use of conventional methods. In this paper we describe a three-step synthesis of Mannich polyols for rigid foams. The first step is synthesis of N-(2-hydroxyethyl)-1,3-oxazolidine (the Mannich precursor) by condensation of paraformaldehyde and diethanolamine. The second step involves synthesis of the Mannich base phenolic ring of cardanol by reaction with N-(2-hydroxyethyl)-1,3-oxazolidine. The third step is alkoxylation. The synthesized polyols were characterized by FTIR and H-1 NMR spectroscopy and thin-layer chromatography.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 16251-45-9. Name: (4S,5R)-4-Methyl-5-phenyloxazolidin-2-one.

Stereoselective synthesis and application of tridentate aminodiols derived from (+)-pulegone

A library of tridentate aminodiols, derived from naturally occurring (R)-(+)-pulegone, was synthesized and applied as chiral catalysts in the addition of diethylzinc to benzaldehyde. The reduction of pulegone furnished pulegol, which was transformed into allylic trichloroacetamide via Overman rearrangement of the corresponding trichloroacetimidate. The protected enamine was subjected to dihydroxylation with OsO4/NMO system resulting in a 1:1 mixture of (1R,2R,4R)- and (1S,2S,4R)-aminodiol diastereomers. After the removal of the trichloroacetyl protecting groups, the obtained primary aminodiols were transformed into secondary ones. The regioselectivity of the ring closure of the N-benzyl substituted aminodiols with formaldehyde was investigated resulting in both the 1,3-oxazine and oxazolidine rings. The tautomerism of the spiro and fused ring systems was observed and its mechanism was studied by detailed DFT analysis by employing an IEFPCM solvent model to provide a more realistic representation of the experimental conditions. The obtained potential catalysts were applied to the reaction of benzaldehyde and diethylzinc with moderate to good enantioselectivity (up to 90% ee). (C) 2016 Elsevier Ltd. All rights reserved.

CoMSIA Studyof a Series of N-dichloroacetyl Oxazolidine Derivatives

Comparative molecular similarity indices analysis (CoMSIA) were performed on N-dichloroacetyl oxazolidine derivatives as herbicide safeners. The best CoMSIA models that were generated using atom based alignmen, R-cv(2)=0.632, n=4, R-2=0.927, F=31.796 and s=0.097. The contributions of steric field, electrostatics field, hydrophobicities field and hydrogenbond acceptor were 0.127, 0.260, 0.285 and 0.328, respectively. The CoMSIA model was satisfactory and would be useful for the future design of new N-dichloroacetyl oxazolidine herbicide safener.

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.

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.

One-pot synthesis of oxazolidine-2-thione and thiozolidine-2-thione from sugar azido-alcohols

A controlled and facile synthesis of various glycosyl 1,3-oxazolidine-2-thiones and 1,3-thiozolidine-2thiones has been accomplished from corresponding sugar azido alcohols utilizing Staudinger reaction (PPh3 and CS2) via isothiocynate route. A series of reactions were performed to investigate the effects of CS2 and PPh3 on the selectivity of product formed. The excessive addition of CS2 with PPh3(1.2 equiv) afforded oxazolidine-2-thione alone, while the solitary addition of PPh3 for 30 min followed by addition of CS2 to the reaction mixture resulted both the products in different ratios, which were successfully isolated using column chromatography (SiO2). Furthermore, synthesis of 1,3-oxathiolan-2-imine from glycosyl epoxide has also been attempted. Structures of all the developed compounds have been elucidated using extensive spectroscopic techniques including IR, NMR and MS analysis. (C)2017 Elsevier Ltd. All rights reserved.

Microwave-assisted synthesis of some hybrid molecules containing penicillanic acid or cephalosporanic acid moieties and investigation of their biological activities

Ethyl 4-amino-2-fluorophenylpiperazin-1-carboxylates containing a 1,3-oxazol(idin)e, 5-thioxo-1,2,4-triazole, 1,3,4-thiadiazole, 5-thioxo-1,3,4-oxadiazole, or 1,3-thiazole nucleus were obtained starting from ethyl piperazine-1-carboxylate (1) by several steps. The treatment of amine, 3 or hydrazide, 9 with several aromatic aldehydes generated the corresponding arylmethyleneamino (3a-f) or arylidenehydrazino (12a-c) compounds. The Mannich reaction between the 1,2,4-triazole or 1,3,4-oxadiazole compounds and 7-aca produced cephalosporanic acid derivatives. Penicillanic acid derivatives were obtained when 6-apa was used in the Mannich reactions. The synthesized compounds were screened for their antimicrobial, antilipase, and antiurease activities. Some of them were found to possess good-moderate antimicrobial activity against the test microorganisms. Two compounds exhibited antiurease activity, and four of them displayed antilipase activity.
