L,4-Androstadiene-3,l7-dione

Selective conversion of l,4-androstadiene-3,l7-dione to 4-androsten-3,17-dione was achieved with (Ph Pi RuClj (SI), prepared by refluxing ruthenium... 

Typically, sterol concentrations of 3 to 4 g 1 are used and incubation times of about lOOh. Yields are dependent upon the species and substrates used. Some data relating to the yields of l,4-androstadiene-3,l7-dione from various sterols and steroids using cultures of Arthrobacter simplex are reported in Table 9.3.
