2,6‐Piperidinediones, II. Absolute Configuration of the Enantiomers of 3,3‐Disubstituted 2,6‐Piperidinediones

Abstract: Determination of the absolute configuration of the 2,6-piperidinediones (+)3a-( +)3e is achieved by correlation of their CD spectra with the spectrum of R(+)-glutethimide. It is shown that (+)3a-(+)3e possess R-configuration. The N-methyl compounds (+)7a and (+)7b, obtained by N-methylation of (+)3a and (+)3b, possess R-configuration, too, and so does (+)3h which is formed by catalytic hydrogenation of (+)3e. The absolute configuration of (+)a can be deduced from the configuration of the starting compound R( +… Show more
