Redox-Annulations of Cyclic Amines with ortho-Cyanomethylbenzaldehydes
摘要:
Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox-neutral annulations with ortho-cyanomethylbenzaldehydes. These amine alpha-C-H bond functionalization reactions are promoted by acetic acid. The resulting beta-aminonitriles can be converted to the corresponding beta-aminoalcohols in diastereoselective fashion.
