Double cyclization of bis(alpha-hetarylmethyl)amino esters to optically active bridged N-heterocycles of HIV-inhibiting activity
Anellated 1-azabicyclo[3.3.1]nonanes 6 were synthesized by several routes starting from natural α-amino esters 2 and ohaloaryl- or o-bromohetarylmethyl bromides 1. N-Alkylation of the starting amino esters to 5 and 3 was followed by halogen/lithium exchange and double cyclization. The cyclization pr...
