Synthesis of 2‘β-Deoxy-[8-13C;amino,9-15N2]adenosine: Unusual Annulation Conditions To Assemble the Purine Core
摘要:
Synthesis of 2'beta-Deoxy-[8-C-13;amino,9-N-15(2)] adenosine has been accomplished using a five-step process which employs a novel annulation of [C-13]formamide [N-(4-[N-15]amino-6-chloro-5-pyrimidinyl)] 2. To effect this dehydration, a complex of triethyl phosphite and TiCl2(i-OPr)(2) was used. 6-Chloro-[8-C-13; 9-N-15]purine was then converted in two steps to 2'beta-deoxy-[8-C-13;amino,9-N-15(2)]-adenosine.
