Tandem Reduction/Cyclization of o-Nitrophenyl Propargyl Alcohols--A Novel Synthesis of 2- & 2,4-
Disubstituted 1,2,3-Triazoles.
A novel tandem reduction/cyclization of o-nitrophenyl propargyl alcohols is described. The reaction proceeds via a radical pathway and provides a convenient access to 2- & 2,4-disubstituted 1,2,3
