A New Pathway for Phthalazine Derivatives via Metal-Free Cyclization of ortho-Alkynylphenyl Ketones and Hydrazine
A one-step synthetic protocol for phthalazine derivatives has been developed. In the presence of Et3N, a series of phthalazine derivatives were conveniently prepared in high yield by the reaction of ortho-alkynylphenyl ketones and hydrazine under mild reaction conditions. The structure was unambiguously confirmed by X-ray crystallographic analysis of product 2i.
