Phosphine-catalyzed activation of cyclopropenones: a versatile C(3) synthon for (3+2) annulations with unsaturated electrophiles
We herein report a phosphine-catalyzed (3 + 2) annulation of cyclopropenones with a wide variety of electrophilic π systems, including aldehydes, ketoesters, imines, isocyanates, and carbodiimides, offering products of butenolides, butyrolactams, maleimides, and iminomaleimides, respectively, in hig...
