A formal total synthesis of pyrrolo[1,4]benzodiazepine anticancer antibiotic family member limazepine E is described. The synthesis features a stereoselective introduction of a trisubstituted double bond using novel sterically demanding Julia–Kocienski reagents, allowing the number of linear steps to be significantly reduced. The potential of the newly developed reagents has also been demonstrated
描述了
吡咯并[1,4]苯并二氮杂anti抗癌抗生素家族成员利马西平E的正式全合成。该合成的特征是使用新颖的对空间要求苛刻的Julia-Kocienski试剂立体选择性地引入三取代双键,从而大大减少了线性步骤的数量。巴莫霉素的正式全合成也证明了新开发试剂的潜力。
