Absolute configuration of 2-hydroxy-2-(1-naphthyl)propionic acid as determined by the 1H NMR anisotropy method

Enantiopure 2-hydroxy-2-(1-naphthyl)propionic acid (+)-2 was prepared by the stereoselective Grignard reaction of 1-naphthylmagnesium bromide with (1R,3R,4S)-menthyl pyruvate 3 or (1R,3R,4S)-8-phenylmenthyl pyruvate 4, and the absolute configuration of acid (+)-2 was unambiguously determined to be S by the 1H NMR anisotropy method.

A direct preparation of N-unsubstituted pyrrole-2,5-dicarboxylates from 2-Azidocarboxylic esters

A new and easy method for synthesis of symmetric pyrrole-2,5-dlcarboxylate derivatives via a simple tltanium(IV)-medlated oxidative dimerlzation of 2-azldocarboxyllc esters is described. The process involves a transformation of tltanium(IV) enolates into

Method for producing optically active amino acid derivative

[PROBLEM TO BE SOLVED]: To provide a method for producing an optically active amino acid derivative which is suitable for the industrial production and handy. [SOLUTION]: The method for producing the amino acid derivative characterized by obtaining the amino acid derivative by reducing compound shown in general formula(1) with hydrogen under the existence of palladium carbon catalyst. (wherein R1 and R2 are the same or different and hydrogen atom, alkyl group, halogen, and amino group, -NHCOR4, -OR4 and -OCOR4; R3 is alkyl group, amino group, -NHCOR4,-OR4, -OCOR4; R4 is hydrogen atom, alkyl group, and aryl group. However, at least one of R1-R3 is above-mentioned - NHCOR4.)

UTILISATION DES ALCOXYTRIALKYLALUMINATES EN SYNTHESE ASYMETRIQUE: SYNTHESE DE L'ACIDE HYDROXY-2, METHYL-2 BUTANOIQUE ENANTIOMERIQUEMENT ENRICHI EN R OU S

The reaction of LiAlEt3OR* with (-)-menthyl pyruvate (R*OH = (-)-N-methylephedrine) and with (+)-menthyl pyruvate (R*OH = (+)-N-methylephedrine) in hexane/ether as solvent produces the corresponding 2-hydroxy-2-methylbutan
