A novel Claisen rearrangement in which the Breslow intermediate is engaged as a hydroxy-substituted N,S-ketene acetal to provide complex 3° alcohols without the use of organometallic reagents is reported. The reaction constitutes an unprecedented reactivity mode for the Breslow intermediate.
报道了一种新的克莱森重排,其中 Breslow 中间体作为羟基取代的N,S-烯酮缩醛参与,以提供复杂的 3° 醇,而无需使用有机金属试剂。该反应构成了 Breslow 中间体前所未有的反应模式。
