Direct vinylation of 2-substituted N-(Benzylidene)glycinonitriles under basic conditions
摘要:
alpha-Vinyl substituted nitriles 5-7 were prepared via addition of carbanions generated from nitriles 1, to acetylene (2) and its derivatives 3 and 4. Subsequent cleavage of nitriles 6 and 7 afforded alpha,beta-unsaturated ketones 8 and 9. Copyright (C) 1996 Elsevier Science Ltd

The α-addition of alcohols to alkynones was demonstrated. A series of α-alkoxy enones can directly be synthesized in moderate to high yields under mild conditions. Mechanism studies were carried out by various means.
