Total synthesis of (-)-(5R,6S)-6-acetoxy-5-hexadecanolide, a major component of mosquito oviposition attractant pheromones is reported. The key synthetic steps involve epoxide opening by lithiated salt of ethylpropionate and acid catalysed lactonization. The total synthesis was achieved in 11 linear steps staring from a readily available carbohydrate delta-gluconolactone in 18% overall yield making
据报道,蚊子产卵引诱剂信息素的主要成分是(-)-(5R,6S)-6-乙酰氧基-5-十六醇。关键的合成步骤涉及通过丙酸乙酯的锂盐的环氧化物开环和酸催化的内酯化。从一个容易获得的碳水化合物δ-葡糖酸内酯开始,在11个线性步骤中完成了总合成,总收率为18%,使其简单,实用和优雅。
