摘要

Methyl 4-trimethylsilyl-3-dialkylaminocrotonate is synthesized by the silylation of methyl 3- dialkylaminocrotonate. It reacts with carbonyl electrophiles at its γ-position. The unusual regiochemistry of this reaction is studied and rationalized. It reacts with enamines derived from acyclic ketones to give aromatic compounds in a 3C+ 3C combination and with enamines derived from cycloketones of 5-to 8-membered rings to give aromatic ...
