Kahweofuran, as an impact flavor component of roasted coffee and possesses the 6-methyl-2,3-dihydrothieno[2,3-c]furan structure, was rapidly synthesized from 2-acetyl-3-hydroxymethylthiophene by the formal reductive cyclization using the Wilkinson’s catalyst. Similarly, the syntheses of the 4-methyl, 6-ethyl and 4,6-dimethyl derivatives were also achieved in favorable yields.
Kahweofuran,作为烘焙咖啡的冲击风味成分,具有6-甲基-2,3-dihydrothieno [2,3- c ]呋喃结构,是通过2-乙酰基-3-羟甲基噻吩通过使用威尔金森的催化剂。类似地,还以有利的产率实现了4-甲基,6-乙基和4,6-二甲基衍生物的合成。
