Heterocycles. 13. Synthesis of [1,2-d]triazolo steroids
Weintraub
, p. 1635 - 1640 (2007/10/02)
Reaction of 1,2-epoxy-5α-3-ketosteroids with sodium azide produces a mixture of expected 2-azido-5α-Δ1-3-ketosteroids and novel [1,2- d]triazolosteroids. A possible pathway for formation of the latter involving 1,3-dipolar cycloaddition of sodi
