Synthesis of 2'beta-Deoxy-[8-(13)C;amino,9-(15)N(2)]adenosine: Unusual Annulation Conditions To Assemble the Purine Core.
Synthesis of 2'beta-Deoxy-[8-(13)C;amino,9-(15)N(2)]adenosine has been accomplished using a five-step process which employs a novel annulation of [(13)C]formamide [N-(4-[(15)N]amino-6-chloro-5-pyrimidinyl)] 2. To effect this dehydration, a complex of triethyl phosphite and TiCl(2)(i-OPr)(2) was used. 6-Chloro-[8-(13)C; 9-(15)N]purine was then converted in two steps to 2'beta-deoxy-[8-(13)C;amino,9-(15)N(2)]adenosine.
