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.

conversion of aldehydes and ketones into alkyl azides by the addition of common organometallic reagents and tandem conversion of the resulting alkoxides without isolation of the intermediate alcohols. A wide range of aldehydes and organometallic reagents (R–Li or R–MgX) are suitable participants in this process. Additional reaction telescoping beyond azide formation is demonstrated.
