Direct entry to peptidyl ketones via SmI2-mediated C-C bond formation with readily accessible N-peptidyl oxazolidinones

(Chemical Equation Presented) In this work, a new method for the preparation of peptidyl ketones is presented employing a SmI2/H 2O-mediated coupling of N-peptidyl oxazolidinones with electron-deficient alkenes. The requisite peptide imides were easily prepared by solution-phase peptide synthesis starting from an N-acyl oxazolidinone derivative of an amino acid. Importantly, they could be used directly in the C-C bond-forming step without the need for further functionalization. Coupling of these peptide derivatives with a second peptide possessing an N-terminal acryloyl group leads to ketomethylene isosteres of glycine-containing peptides. This method represents an alternative means for ligating two small peptides through a C-C bond-forming step.

Facile and efficient addition of terminal alkynes to benzotriazole esters: Synthesis of d-erythro-sphingosine using ynones as the key intermediate

From the perspective of synthesis, ynones are compounds of considerable interest because of their occurrence in a wide variety of biologically active molecules and as key synthetic intermediates. In this context, a facile and highly efficient synthesis of ynones was developed based on the high reactivity of benzotriazole esters formed in situ. Lithium acetylides can alkylate various carboxylic acids in yields ranging from 60% to 92%. To determine whether our methodology is useful for synthesising complex and biologically relevant molecules, we synthesise d-erythro-sphingosine in four steps and with 33% overall yield from l-serine.

Synthesis and in vitro pharmacology of novel heterocyclic muscarinic ligands

A set of novel heterocyclic ligands (7a-9a, 7b-9b, and 9c) structurally related to oxotremorine 2 was designed, synthesized, and tested at muscarinic receptor subtypes. In the binding experiments at cloned hm1-5, the presence of the 2-methylimidazole/2-methyl-3-alkylimidazolium moiety in place of the pyrrolidine ring revealed, in derivatives 8a, 8b, and 9c, a moderate selectivity for some receptor subtypes. The functional in vitro assays yielded results that correlated closely to binding data. In general, on passing from agonists bearing the pyrrolidine moiety to their analogues carrying the 2-methylimidazole function, the overall pharmacological efficacy profile is shifted from agonism toward partial agonism. The insertion of the 2-methyl-3-alkylimidazolium moiety advances the effect such that the compounds are pure antagonists. Quite similarly, chiral 3-oxo-Delta 2-isoxazoline (¡À)-10 behaved as a weak antagonist unable to discriminate the different muscarinic receptor subtypes.

Absolute configuration of lactams and oxazolidinones using kinetic resolution catalysts

A simple method for determining the absolute configuration of oxazolidinones, lactams, and their derivatives using kinetic resolution catalysts is described. The optically pure substrates were acylated using the (S)-HBTM and the (R)-HBTM catalyst, and the faster reaction was determined. An empirical mnemonic was developed for the assignment of the absolute configuration based on the fast-reacting catalyst.

Synthesis of (+)-didemniserinolipid B: Application of a 2-allyl-4-fluorophenyl auxiliary for relay ring-closing metathesis

(Chemical Equation Presented) The synthesis of didemniserinolipid B utilizing a ketalization/ring-closing metathesis (K/RCM) strategy is described. In the course of this work, a novel 2-allyl-4-fluorophenyl auxiliary for relay ring-closing metathesis (RRCM) was developed, which increased the yield of the RCM. The resulting 6,8-dioxabicyclo[3.2.1]octene core was selectively functionalized by complimentary dihydroxylation and epoxidation routes to install the C10 axial alcohol. This bicyclic ketal core was further functionalized by etherification and an alkene cross metathesis with an unsaturated a-phenylselenyl ester en route to completing the total synthesis.

Provided is a process which comprises reacting a 2-hydroxycarboxylic acid ester with urea to form a 2,4-oxazolidinedione , separating an unreacted 2-hydroxycarboxylic acid ester and a catalyst from the resulting reaction solution through distillation, and purifying the fraction composed mainly of the 2,4-oxazolidinedione through crystallization and/or extraction. In accordance with the present invention, the purified 2,4-oxazolidinedione is easily produced in a high yield by a simple purification method without using a costly alkali metal compound.

Enhanced enantiocontrol in catalytic metal carbene transformations with dirhodium(II) tetrakis, Rh2(4S-MEOX)4

The synthesis, spectral characteristics, and X-ray structures for dirhodium(II) tetrakis, Rh2(4S-MEOX)4, and the related dirhodium(II) tetrakis, Rh2(4S-THREOX)4, are reported.Comparison is made between these 2-oxooxazolidin-ligated dirhodium(II) catalysts for metal carbene transformations and those with comparable 2-oxopyrrolidine ligands, especially dirhodium(II) tetrakis, Rh2(5S-MEPY)4.Structure-selectivity comparisons reveal that Rh2(4S-MEOX)4 provides higher enantiocontrol and, in some cases, higher diastereocontrol than Rh2(5S-MEPY)4 in intramolecular carbon-hydrogen insertion reactions of sterically demanding diazoacetates and diazoacetamides and is the catalyst of choice for highly enantioselective diazodecomposition of adamantyl diazoacetates and N-(tert)butyldiazoacetamides.The structurally analogous Rh2(4S-THREOX)4 is nearly identical with Rh2(4S-MEOX)4 in its overall effect on selectivity.The net advantage of Rh2(4S-MEOX)4 lies in its wider openness for metal carbene transformations.
