α,β-Unsaturated acyl cyanide synthesis via triethylamine catalyzed redox cyanation

Autor: Min Seok Jung, Young Hoon Son, Eun Joo Kang, Hyung Ho Choi

Publikováno v: Tetrahedron Letters. 52:2312-2315

Stereoselective redox cyanation of alkynyl aldehydes was explored, furnishing (E)-α,β-unsaturated acyl cyanides. This reaction was catalyzed by mild TEA base, as a dual role of Lewis base and Bronsted base. TMSCN treated with TEA was an effective r
