Herein, we report asymmetric allylic substitution-isomerization for the regio- and atroposelective synthesis of axially chiral N-vinylquinazolinones. The catalysis system was achieved by means of asymmetric transition-metal catalysis and organocatalysis which afforded trisubstituted as well as E- and Z-tetrasubstituted N-vinylquinazolinone atropisomers, respectively.

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.

The Morita-Baylis-Hillman reaction of aldehydes with alpha,beta-unsaturated ketones can be affected by the Lewis bases. We have found that 1-methylimidazole 3-N-oxide promoted the Morita-Baylis-Hiliman reaction of various activated aldehyde compounds in non-solvent system. This is a mild reaction condition and requires no special equipment to give the Morita-BaylisHillman adducts. (C) 2005 Elsevier Ltd. All rights reserved.

1,1-Carbonyldiimidazole-promoted coupling of Baylis-Hillman-derived indolizine-2-carboxylic acids with a range of amine and amino acid derivatives has provided access to the corresponding carboxamides in moderate to excellent yield.
