The copper-catalyzed azide-alkyne cycloaddition (CuAAC) has been
used for the construction of 1,2,3-triazole containing steroids
in good to excellent yields. Combination of propargylic glycosides
and steroidal azides as reaction partner allowed the synthesis of
a privileged class of natural product analogues. The versatility
of this protocol makes this chemistry a useful attractive approach
for the synthesis of target molecules.
