Enantioselective total synthesis of (+)-epiepoformin 1, (+)-epiepoxydon 2 and (+)-bromoxone 3 using a chiral building block, ethyl (1R,2S)-5,5-ethylenedioxy-2-hydroxycyclo- hexanecarboxylate 6, is described. Since the synthesis afforded intermediates 18, 2 and 25, it accomplished a formal synthesis of (−)-theobroxide 19, (−)-phyllostine 22, (+)-herveynone 27 and (−)-asperpentyn 28. The usefulness of
使用手性结构单元(1 R,2 S)-5,5-乙撑二氧基-2-羟基环己烷甲酸乙酯对映体选择性合成(+)-表二甲双胍1,(+)-表氧双酚2和(+)-溴酮3参照图6进行说明。由于合成,得到中间体18,2和25,它完成的正式合成( - ) - theobroxide 19,( - ) - phyllostine 22,(+) - herveynone 27和( - ) - asperpentyn 28。证明了6对于合成天然环氧环己烯衍生物的有用性。
