摘要

Notes J. Org. Chen., Vol. 47, No. 19, 1982 3789 conformational A values for CH3 (1.74 kcal/mol) and Sn-(CH,),(1.0 kcal/mol) 1 B would be expected to predominate.(The chemical shift of C-CH3 (20.08 ppm) also indicates a substantial population of A, but notice (Table I) the C-CH3 shift of 19.14 ppm in the corresponding silyl ketone (XI), for which the conformation analogous to A is more dominant, as expected for the" larger" 11 (CH3) 3Si ...
