Zinc-Mediated Highly α-Regioselective Prenylation of Imines with Prenyl Bromide
摘要:
A highly alpha-regioselective prenylation of imines has been successfully developed. The efficiency of this approach is confirmed by a wide range of imines including N- and C-aryl aldimines, N-alkyl aldimines, C-alkyl aldimines, and N- and C-aryl ketimines. The approach uses prenyl bromide as the prenyl source and inexpensive and convenient zinc as the mediator as well as environmentally benign 1,3-dimethyl-2-imidazolidinone (DMI) as the solvent.

homoallylamines through H2SO4-mediated intramolecular cyclization. The advantages of this transformation include mild reaction conditions, experimental simplicity, its solvent- and metal-free, atom- and step-economical nature, and the use of a readily available, cheap, and nontoxic mediator. The biologically important tetrahydro-1-benzazepine skeleton was conveniently constructed from N-arylated homoallylamines
