One-pot reaction of ortho-acylphenols and terminal alkynoates for synthesis of 2-alkyl-substituted chromanones
摘要:
A facile synthesis of 2-alkyl-substituted chromanones from ortho-acylphenols and terminal alkynoates is described. The method contains two consecutive processes in one-pot reaction through a DABCO-catalyzed condensation reaction and a KOBu'-mediated intramolecular cycloaddition to afford the desired products.

已开发出碘促进的一锅级联氧化环化反应,用于从邻乙酰苯氧基丙烯酸酯、四氢异喹啉和去甲列宁合成色酮稠合吡咯并[2,1 - a ]异喹啉和吲哚并[8,7- b ]吲哚. 该过程对色酮稠合的吡咯并[2,1- a ]异喹啉和色酮稠合的吲哚嗪[8,7- b ]吲哚异层板林衍生物均采用了合乎逻辑的方法。的手法升-薄荷醇和DL -α生育酚证明这种策略的应用。
