A new carbene-catalyzed [4 + 2] annulation of 2H-azirine-2-carbaldehydes with ketones was developed, thus providing the 2,3-dihydro-6H-1,3-oxazin-6-one core structures with broad scope and good to excellent yields. Notably, the azolium aza-dienolates gene

Preparation of 2-(phosphoranylideneamino)acrylaldehydes, novel formyl-substituted (vinylimino)phosphoranes, was accomplished by the reaction of formyl-2H-azirines with triphenylphosphine. Their novel pyridine-formation reactions with acetylenic esters ach
