The use of 1 M NaOMe as a base exclusively affords both (E)- and (Z)-3-alken-1-ynes with high regio- and stereoselectivity, while the use of LiOH・H2O instead of 1 M NaOMe preferentially gives both (E)- and (Z)-1-trimethylsilyl-3- alken-1-ynes regio- and stereoselectively., application/pdf}, pages = {1101--1104}, title = {Construction of Terminal Conjugated Enynes: Regio- and Stereoselective Syntheses of 3-Alken-1- ynes and 1-Trimethylsilyl-3-alken-1-ynes from Alkenyldialkylboranes and (Trimethylsilyl)ethynyl Bromide}, volume = {2002}, year = {2002} }
