The synthesis of 7-epi-pinguisone (2) from (S)-(+)-2,3,7,7a-tetrahydro-7a-methylindene-1,5(6H)-dione (4) is described. The acylation of a carbanion derived from the conjugated addition of lithium dimethylcuprate to an αβ-unsaturated ketone is re-investigated. A new synthesis of condensed β-furanones is illustrated.
描述了由(S)-(+)-2,3,7,7a-四氢-7a-甲基茚满-1,5(6 H)-二酮(4)合成7- Epi- pinguisone(2)。重新研究了由共轭加成的二甲基二甲基碳酸锂加成到αβ-不饱和酮上所产生的碳负离子的酰化作用。说明了缩合的β-呋喃酮的新合成。
