摘要：

Lewis acid-promoted triethylsilane reduction of 6,6-spiroketol alcohols produces cis-2,6-disubstituted tetrahydropyrans with excellent regioselectivity and stereocontrol. An appended alcohol allows bidentate coordination of the Lewis acid to selectively activate one CO bond of the anomeric center toward reductive cleavage. Copyright (C) 1996 Elsevier Science Ltd
