Facile Baylis-Hillman reaction of substituted 3-isoxazolecarbaldehydes: The impact of proximal heteroatom within a heterocycle on the acceleration of reaction

The fast and facile Baylis-Hillman reaction in substi-tuted 3-isoxazolecarbaldehydes confirms the impact of the proxi-mal heteroatom within a heterocycle towards enhanced reactivity of the formyl group for this reaction

Baylis-Hillman reaction assisted synthesis of substituted 5,8-dihydro-isoxazolo[4,5-c]azepin-4-one: A novel isoxazole-annulated heterocycle

The novel synthesis of a new isoxazole-annulated heterocycle namely 5,8-dihydro-isoxazolo[4,5-c]azepin-4-one described herein is based on the reaction of benzyl amine with acetates of Baylis-Hillman adducts generated from 3-aryl-5-formyl-isoxazole-4-carboxylate
