one-pot Staudinger/aza-Wittig/Castagnoli-Cushman reaction sequence for a series of azido aldehydes and homophthalic anhydrides is described. The reaction proceeded at room temperature and delivered novel polyheterocycles related to the natural product realm in high yields and high diastereoselectivity. The methodology has been extended to three other cyclic anhydrides. These further unravel the potential
描述了一系列叠氮醛和高邻苯二甲酸酐的单锅施陶丁格/aza-Wittig/Castagnoli-Cushman 反应序列的实现。该反应在室温下进行,并以高产率和高非对映选择性提供与天然产物领域相关的新型多杂环化合物。该方法已扩展到其他三种环状酸酐。这些进一步揭示了 Castagnoli-Cushman 反应在生成多杂环分子支架方面的潜力。
