Abstract

A series of dihydro-4-[2,3-b]pyridine-5-carbonyl)L-alpha-amino esters(5) have been prepared via the respective thieno[2,3-b]pyridinyl-5-carbonyl chloride (4). The CD spectra of the L-aliphatic (5a-d) and L-aromatic (5e-g) alpha-amino acid derivatives display in organic solvents, sign inversion of the measured Cotton effect (CE) bands. This chiroptical behaviour is probably associated with differences in conformational isomerism of either set. MS and NMR spectral data of the title compounds are presented.
