Abstract: The sequence of p'lithiation and electrophilic substitution of a,@-unsaturated secondary and tertiary amides is reported to provide a convenient method for selective p'functionalization of a, P-unsaturated acid derivatives. Lithiation with sec-BuLi/TMEDA of N- methyl-1-cyclohexenecarboxamide (19), N-methyl-1-cyclopentenecarboxamide (30), N, N- diisopropyl-1-cyclohexenecarboxamide (36), N, N-diisopropyl-6-(trimethylsilyl)-l- ...
