Abstract

Functionalization at C-5 of the triacetic acid lactone methyl ether, 7, has been achieved by a transfer from the C-6 position. Thus, treatment of sulfides 12 with an excess of ethyl diazoacetate provides the pyrones 15 through [2,3]sigmatropic rearrangements. © 1984, Taylor & Francis Group, LLC. All rights reserved.
