Abstract The regio-and diastereoselectivity of reactions of selected α-(1-hydroxyalkyl)acrylate derivatives with sodium methanethiolate have been investigated. The hydroxy compounds typically undergo conjugate addition with up to 66% d.e., while the acetoxy and bromo analogues favour SN' and SN reactions, respectively.

The influence of substituents and temperature on the thermalcyclisation of 3-acetoxy-2-methylene-3-(2-pyridyl)propanoic esters and analogues has been explored using 1H NMR spectroscopy, and mechanistic proposals for the formation of the resulting indolizines are presented.

Selective Hydrogenation of Indolizines: An Expeditious Approach To Derive Tetrahydroindolizines and Indolizidines from Morita–Baylis–Hillman Adducts

In this study, we describe the hydrogenation of indolizines derived from Morita-Baylis-Hillman adducts. We demonstrate that functionalized tetrahydroindolizines and indolizidines can be prepared selectively, at low pressure, by simply adjusting the acidity of the medium. Using this simple and straightforward strategy, substituted tetrahydroindolizines and indolizidines were obtained diastereoselectively in high yield.
