Ozonolysis of a variety of (tetraydrofuran-2-yl)tri-n-butylstannanes a
ffords the corresponding gamma-butyrolactones in good to excellent yie
lds, This reaction is tolerant to a range of other functional groups a
nd provides access to substituted gamma-butyrolactones not available f
rom aldol reactions of the parent lactone. Copyright (C) 1996 Elsevier
