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 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
Stereodivergent synthesis of 2-alkynyl buta-1,3-dienes using Sonogashira coupling with controllable retention or inversion of olefin geometry

A stereodivergent approach to 2-alkynyl buta-1,3-dienes from a single stereoisomer of starting α-bromoenal has been developed. By simply switching the sequence of Sonogashira and Horner-Wadsworth-Emmons reactions, it is possible to obtain these branched d
