(+) and (−)-Goniofufurones, (+) and (−)-8-epi-goniofufurones have been synthesized from d-(−) and l-(+)-tartaric acids by the addition of ethyl lithiopropiolate to a chiral aldehyde intermediate as a key step, in which LDA is the best base compared to n-BuLi plus Lewis acid YCl3 (cat.).
(+)和(-)-Goniofufurones,(+)和(-)-8- Epi- goniofufurones是由d-(-)和l-(+)-酒石酸通过将硫代丙酸乙酯添加至手性化合物而合成的醛中间体是关键步骤,其中LDA是与正丁基锂加路易斯酸YCl 3(目录号)相比最好的碱。
