Abstract
TiCl-ing your fancy: A simple and highly efficient synthetic method for the preparation of indolizines from the reaction of 2-enoylpyridines with sulfonamides in the presence of TiCl4 under mild conditions has been developed. A subsequent phosphine-catalyzed aza-Michael reaction of the corresponding indolizines with vinyl ketones and activated allenes was also developed, which affords highly functionalized indolizines in excellent yields under mild conditions.
