摘要：

Two complementary approaches have been realized for the stereoselective synthesis of 4,6-disubstituted delta-lactones and 1,3-anti and syn diols. In the 6-endo selenolactonization the role of the V ion on the stereoselectivity is shown. Moreover, the highly stereoselective transformation of the 6-endo delta-lactone to the 5-exo gamma-lactone is reported. (C) 2002 Elsevier Science Ltd. All rights reserved.
