1,26,27 Addition products with Nu=vinyl and ethynyl, which were mixtures of two stereoisomers, were hydrogenated to the corresponding C-ethyl products. Either the major (ethynyl) or the minor (vinyl) component of the mixture of hydrogenated products was found identical with one of compounds 21, 23 or 24. Compounds 27-30 and 33-36 were correlated with compounds 32 and 38. The absolute configurations of the two latter compounds were deduced from the fact that they were neither identical nor enantiomeric to, respectively, 20 and 26.

19. Ab initia calculations were performed with the GAUSSIAN92 program. Complexes and transition structure geometries were located with full optimization with the HF/3-21G basis set and characterized in each case by means of a vibrational frequency analysis.
