An efficient strategy for the conversion of biomass derived 5‐hydroxymethylfurfural (HMF) into 2‐hydroxy‐3‐methylcyclopent‐2‐enone (MCP) by an intramolecular aldol condensation of 1‐hydroxyhexane‐2,5‐dione (HHD) has been developed. Further transformations of MCP towards the diol, enol acetate, levulinic acid and N‐heterocyclic compounds are also reported.

5-羟基甲基糠醛经1-羟基己烷-2,5-二酮为中间体的环戊酮衍生物

一种有效的策略是通过1-羟己烷-2,5-二酮（HHD）的分子内醇醛缩合将生物质衍生的5-羟甲基糠醛（HMF）转化为2-羟-3-甲基环戊-2-烯酮（MCP）发达。还报道了MCP向二醇，乙酸烯醇酯，乙酰丙酸和N杂环化合物的进一步转化。
