Several vinylboranes were explored as trans-1,2-dihydroxyethylene equivalents for Diels-Alder reactions. Use of the 1,2-bis(boryl)ethylene 4 allows the direct formation of 1,2-dihydroxycyclohexenes in high yield. The 2-phenyldimethylsilylvinylborane 8 is a good alternative that allows for hydroxyl-group differentiation.
探索了几种乙烯基硼烷,作为Diels-Alder反应的反式-1,2-二羟基乙烯当量。1,2-双(硼基)乙烯4的使用可以高产率直接形成1,2-二羟基环己烯。2-苯基二甲基甲硅烷基乙烯基硼烷8是允许羟基区分的良好选择。
