Studies toward the construction of substituted piperidine-2-ones and pyridine-2-ones from Baylis-Hillman adducts: Discovery of a facile synthesis of 5-methyl-4-oxo-6-aryl-3-aza-bicyclo[3.1.0]hexane-1-carboxylates

Studies toward the construction of functionalised piperidone derivatives from derivatives of Baylis-Hillman adducts are described. Interestingly the 6-oxo-4-aryl-piperidine-3-carboxylates generated during the study serve as precursor for the facile synthesis of 4-oxo-6-aryl-3-aza-bicyclo[3.1.0]hexane-1-carboxylates

A facile route to the synthesis of novel 2-amino-1,4,5,6-tetrahydropyrimidines from Baylis-Hillman products of acrylonitrile

A facile route for the synthesis of novel 5-substituted-2-amino-1,4,5,6-tetrahydro pyrimidines from the Baylis-Hillman adducts obtained from reaction of aldehydes and acrylonitrile is described.
