convenient procedure for the synthesis of homoallylic alcohols from carbonyl compounds and allylboranes is described. Allyl-, 2-methylallyl-, crotyl- and 3,3-dimethylallyl(dialkyl)boranes, as well as diallyl(alkyl)boranes and derivatives of 3-allyl- and 3-metallyl-3-borabicyclo[3.3.1]non-6-ene are effective reagents for allylation of carbonyl compounds (aldehydes, ketones, esters, carboxylic acids and others)
描述了一种从羰基化合物和烯丙基硼烷合成均烯丙基醇的简便方法。烯丙基,2-甲基烯丙基,巴豆基和3,3-二甲基烯丙基(二烷基)硼烷,以及二烯丙基(烷基)硼烷和3-烯丙基和3-金属烯丙基-3-borabicyclo [3.3.1] non的衍生物-6-烯是用于羰基化合物(醛,酮,酯,羧酸等)的烯丙基化的有效试剂,在许多情况下,与使用相应的烯丙基卤化镁相比,具有相当大的优势。羰基化合物的烯丙基硼化与烯丙基重排有关。同时将巴豆基和3,3-二甲基-烯丙烯酮反应成具有末端双键的均烯丙基醇。
