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
