  A Stereocomplementary Approach to β-Lactones:  Highly Diastereoselective Synthesis of cis-β-Lactones, a β-Chloro Acid, and a Tetrahydrofuran

  摘要：

  [GRAPHICS]In the course of mechanistic studies of the ZnCl2-mediated tandem Mukaiyama aldol-lactonization reaction of aldehydes and thiopyridyl ketene acetals, a stereocomplementary reaction employing SnCl4 was discovered. This method provides a highly diastereoselective entry to cis-1,2-disubstituted beta-lactones as well as a beta-chloro carboxylic acid and a tetrahydrofuran. The former products were obtained by varying the reaction temperature. The latter product was obtained when the aldehyde substrate bore a pendant silyl ether.

  A concise and highly diastereoselective route to β-lactones has been developed based on a tandem Mukaiyama aldol-lactonization employing thiopyridylsilylketene acetals and various aldehydes. (−)-Panclicin D, a potent pancreatic lipase inhibitor, was synthesized using this methodology. Recent optimization and extensions of this method are described which include variation of the silyl group and leaving
