Allene l,3-dicarboxylic esters and acids have been converted into chromenes, chromones, on a-pyrone and a coumarin by reactions with phenols and to quinolones by reaction with aniline derivatives. A novel chromene → coumarine rearrangement is also reported.
通过与苯酚的反应,在α-吡喃酮和香豆素上,丙二烯1,3-二羧酸酯和酸已被转化为色烯,色酮,并通过与苯胺衍生物的反应而转化为喹诺酮。还报道了新的色烯→香豆碱重排。
