Synthesis of 5-membered heterocycles using benzoylacetonitriles as synthon

摘要

This review article represents a survey covering the synthetic strategies leading to 5-membered heterocycles. The reactions are subdivided into groups that cover the synthetic methods of those heterocycles, i.e. pyrroles, furans, thiophenes, pyrazoles, isoxazoles, thiazoles, and others, utilizing benzoylacetonitriles as starting precursor from 1985 up to the present. The reactions are subdivided into groups that cover the synthetic methods for those heterocycles from benzoylacetonitriles.
