The Ireland–Claisen rearrangement is the central step in the synthesis of tubuphenylalanine, a key building block of the highly antitumor-active tubulysins. The rearrangement of substituted β-amino acid allyl esters, in combination with subsequent decarboxylation and oxidative cleavage of the double bond, allows the highly stereoselective introduction of substituents into the α-position of the resulting
爱尔兰-克莱森重排是合成微管苯丙氨酸的关键步骤,微管苯丙氨酸是抗肿瘤活性高的微管溶素的重要组成部分。取代的β-氨基酸烯丙基酯的重排,与随后的双键的脱羧和氧化裂解相结合,使得可以高度立体选择性地将取代基引入所得γ-氨基酸的α-位。
