摘要：

The use of magnesium chloride as initiator makes it possible to synthesize dihydrofuran‐2,3‐diones 1 or their tautomers, the alkylidenebutenolides 2, according to (a) in greater than 60% yields. Whether 1 or 2 is isolated depends on the R2 group. All reaction steps are regio‐ and stereospecific. (Figure Presented.) Copyright © 1990 by VCH Verlagsgesellschaft mbH, Germany
