The preparation of the following steroid phosphorodichloridates is described: cholestanyl, epicholestanyl, epicholesteryl, and the derivatives of methyl 3α-hydroxy-5β-chlolanate, and ergosta-8 (14) en-3β-ol. The formation of the phosphorodichloridates was followed by tlc Attempted phosphorylation of 3, 5-cyclocholestan-6β-ol, and 6β-hydroxycholest-4-en-3-ol gave cholesteryl phosphorodichloridate and cholestane 3, 6-dione respectively.
