4-exo-dig cyclocarbopalladation: A straightforward synthesis of cyclobutanediols from acyclic γ-bromopropargylic diols under microwave irradiation conditions
Bour, Christophe,Suffert, Jean
, p. 1390 - 1395 (2006)
Treatment of acyclic γ-bromopropargylic diols with tributyl-stannylated alkynes under palladium catalysis and microwave irradiation conditions gives high yields of the bis(alkylidene)cyclobutanediol derivatives and cyclobutenediols through an efficient 4-exo-dig cyclocarbopalladation. The cyclization is general with a wide variety of alkyne derivatives and gives access to new cyclobutane ring systems bearing one exocyclic double bond and one eneyne substituent as well as bicyclic dienes sharing a common double bond that may be of interest for further elaborations of complex molecules.

A DMAP (2-dimethylaminopyridine)-catalyzed condensation reactions for the successful direct construction of pyrimido[1,2-a]benzimidazole or imidazo[1,2-a]pyrimidine has been developed. The method utilizes readily available α-bromocinnamaldehydes with 2-am

A visible-light-promoted metal-free catalytic system was developed to achieve the aminothiolation of α-bromocinnamaldehydes. This mechanistically novel approach allows the synthesis of diverse imidazo[2,1-b]thiazole derivatives in satisfactory yields at r
