内容記述タイプ Abstract
内容記述 The cross-coupling reaction of (E)- and (Z)-alk-1-enyldialkylborane with (trimethylsilyl)ethynyl bromide proceeds in the presence of a catalytic amount of Cu(acac)_2 and a base under extremely mild conditions to provide conjugated enynes whose carbon-carbon triple bond is distal position. The use of 1M NaOMe as the base results in not only cross-coupling but also desilylation affording both (E)- and (Z)-alk-3-en-1-ynes exclusively, while the use of LiOH・H_2O instead of 1M NaOMe preferentially gives both (E)- and (Z)-1-(trimethylsilyl)alk-3-en-1-ynes with high regio- and stereoselectivity. On the other hand, the cross-coupling reaction of (Z)-1-(trimethylsilyl)alk-1-enyldicyclohexylborane with (trimethylsilyl)ethynyl bromide proceeds in the presence of a small amount of CuI and aqueous NaOH under extremely mild conditions to afford (Z)-1,3-bis(trimethylsilyl)alk-3-en-1-yne with high regio- and stereoselectivity. In addition, treatment of the resultant product with 1M NaOMe leads to the stereoselective formation of (Z)-3-(trimethylsilyl)alk-3-en-1-yne in a one-pot manner.
