A convergent enantioselective synthesis of penicimarin B, aspergillumarin A and B has been reported using Brown’s allylation, DeBrabander–Bhattacharjee lactonization and Grubbs cross coupling metathesis. During this synthesis we have standardized the conditions for DeBrabande–Bhattacharjee lactonization to obtain excellent yield (>90%).
已经报道了使用布朗的烯丙基化,DeBrabander-Bhattacharjee内酯化和Grubbs交叉偶联易位,对青霉素B,曲霉芦丁A和B会聚的对映选择性合成。在该合成过程中,我们已经标准化了DeBrabande–Bhattacharjee内酯化的条件,以获得优异的收率(> 90%)。
