Conjugate Hydrocyanation of Chalcone Derivatives Using Ethyl Cyanoacetate as an Organic Cyanide Source
作者:Zheng Li、Junjun Yin
DOI:10.1002/cjoc.201600860
日期:2017.7
The conjugate hydrocyanation of chalcone derivatives using ethyl cyanoacetate as an organic cyanide source at room temperature under open air and transition metal‐free conditions was described. The protocol has advantages of using relatively cheap, less toxic, stable and easy‐to‐handle cyanating reagent, high yield, and mild reaction condition.
Microwave assisted synthesis of dihydropyridazin-3(2H)-ones and the subsequent dehydrogenation using seleniumdioxide are described.

nickel-catalyzed, high atom- and step-economical reaction of cyanohydrins with aldehydes or ketones via an unprecedented “cyano-borrowing reaction” has been developed. Cleavage of the C–CN bond of cyanohydrins followed by aldol condensation and conjugate addition of cyanide to α,β-unsaturated ketones proceeded to deliver a range of racemic β-cyano ketones with good to high yields. The practical procedure
