[4+2] Cycloaddition Reactions of Neutral 2-Azadienes with Electron-deficient Dienophiles
摘要:
A method for the preparation of functionalized tetrahydropyridine and triazine derivatives is described, based on aza Diels-Alder reaction of neutral 2-aza-1,3-dienes with electron-poor dienophiles as tetracyanoethylene and N-phenyl-1,2,4-triazoline-3,5-dione.
