Steroids and related studies. Part XX. 4,17a-Diaza-D-homo-steroids
Abstract
Oxidation of 17a-aza–D-homoandrost-4-ene-3,17-dione with sodium periodate–potassium permanganate yields 5,17-dioxo-l7a-aza-;D-homo-A-nor-3,5-secoandrostan-3-oic acid which has been used to prepare some 4,17a-diaza-D-homo-steroids. We report the synthesis of 4,17a-dimethyl-4,17a-diaza–D-homo-5α-androstane dimethiodide (HS-342), which possesses neuromuscular-blocking activity.
