The feasibility of using the Mitsunobu reaction for coupling of purines with steroids to obtain nucleosteroids was investigated in the particular case of 6-chloropurine and cholesterol. Three principal products were obtained: 3βbT-(6-chloropurin-9-y

Several nucleocyclitols were synthesized in good yield from an inositol epoxide and some activated purine derivatives (adenine, 6-methylmercaptopurine). The reaction was also carried out with other more basic, nitrogen heterocycles such as imidazole

Steroidal nucleoside analogs were synthesized starting from testosterone. By reduction of the oxime of 17 beta-hydroxy-androst-4-en-3-one (testosterone), a mixture of the two amino epimers of C-3 were obtained. The 3 alpha-amino-androst-4-en-17 beta-

The reaction of 16 alpha,17 alpha-epoxy-3 beta-hydroxy-5-pregnen-20-one with 6-methyl thiopurine activated with sodium hydride leads to the coupling of the purine base with the carbonyl group at C-20 to give a steroidal nucleoside analog, which is te
