Abstract

Pyrimidinone, thioxopyrimidinone, pyrimido[2,1-a]phthalazinone and [1,3]oxazino[2,3-a] isoindolone were obtained by means of microwave-assisted [4+2] cycloreversion. The microwave heating of the parent norbornene or oxanorbornene fused compounds in a solvent with a medium or large loss factor generates retro Diels-Alder products in excellent yield and high purity.

Keywords: Microwave, retro Diels-Alder reaction, N,N-, O,N-heterocycles
