(+) and (-)-Goniofufurones, (+) and (-)-8-epi-goniofufurones have been synt
hesized from D-(-) and L-(+)-tartaric acids by the addition of ethyl lithio
propiolate to a chiral aldehyde intermediate as a key step, in which LDA is
the best base compared to n-BuLi pins Lewis acid YCl3 (cat.). (C) 2001 Els
