Abstract

Abstract The syntheses of (S)-(-)-1, 2-dimethyl-1, 2, 3, 4-tetrahydroisoquinoline (IX) and (S)- (+)-2, 3-dimethyl-1, 2, 3, 4-tetrahydroisoquinoline (XVI)[via (S)-1-benzoyl-N-ethoxycarbonyl ethylamine (XI)] in optically pure form and with known absolute configuration is described. The CD and NMR spectra of these compounds and of most of their intermediates are given, and from these data could be deduced, that the N-methyl groups of the two bases IX and ...
