A versatile and stereoselective total synthesis of (+) and (-) pentenomycin I, (+) halopentenomycins I and dehydropentenomycin from a common chiral polyhydroxylated cyclopentene through oxidation and protection/deprotection has been described. Stereoselective hydroxymethylation, stereoselective Grignard reaction and ring closing metathesis are the key features of our approach.
已报道了一种通用且立体选择性的全合成方法,通过氧化以及保护/脱保护反应,从一种常见的手性多羟基化环戊烯出发,合成(+)和(-)戊霉素I、(+)卤代戊霉素I以及脱氢戊霉素。立体选择性羟甲基化、立体选择性格氏反应和闭环复分解反应是我们方法的关键特征。
