Synthesis of vinyldihydropyran by cooperative catalysis
5-Unsaturated aldehydes with a suitably positioned allylic halide, or phosphate, leaving group undergo doubly-catalyzed cyclization to give dihydropyran derivatives. The cyclization proceeds under the synergetic action of diazabicycloundecene and Pd(PPh3)4. This type of transformation w...

Summary: | 5-Unsaturated aldehydes with a suitably positioned allylic halide, or
phosphate, leaving group undergo doubly-catalyzed cyclization to give
dihydropyran derivatives. The cyclization proceeds under the synergetic
action of diazabicycloundecene and Pd(PPh3)4. This type of transformation
was also accomplished with an aryl ketone. [Projekat Ministarstva nauke
