An efficient and concise stereoselective total synthesis of naturally occurring (-)-cis-aerangis lactone and (-)-cis-cognac lactone is described. The Sharpless asymmetric epoxidation of a primary allylic alcohol and TBSOTf-mediated intramolecular hydride transfer of a chiral epoxy alcohol have been successfully utilized for the construction of a key precursor with syn-aldol stereochemistry using a
描述了天然存在的(-)-顺式-aerangis内酯和(-)-顺式-白兰地内酯的有效和简洁的立体选择性全合成。伯烯丙基醇的Sharpless不对称环氧化和手性环氧醇的TBSOTf介导的分子内氢化物转移已成功地用于通过非醛醇途径合成顺醇醛立体化学的关键前体。 内酯-维蒂希烯烃-尖锐的不对称环氧化-分子内氢化物转移-顺式-羟醛
