  1,4-Reductive Addition of Hydrazoic Acid to γ-Oxo-α,β-unsaturated δ-Lactones and -Lactams: A Convenient Route to α-Amino-γ-oxo-α,β-unsaturated δ-Lactones and -Lactams

  摘要：

  gamma-Oxo-alpha,beta-unsaturated delta-lactones and lactams, which are easily accessible from their corresponding 2-furylcarbinols, were used as substrates for the 1,4-reductive addition of hydrazoic acid. The outcome of the reaction is the formation, in high yields, of the corresponding alpha-amino-gamma-oxo-alpha,beta-unsaturated delta-lactones and -lactams, compounds of great biological and synthetic interest.

  5-methylene-2(5H)-furanone derivatives are easily obtained by treatment of tertiary 2-furylcarbinols with pyridinium dichromate in dimethylformamide solution. Through this procedure, a natural product, the thiophene lactone isolated from Chamaemelum Nobile L., has been synthesized.
