  摘要：

  Wittig treatment of 3',5'(or 2',5')-bis-O-silyl-2'(or 3')-ketoadenosine derivatives with methylenetriphenylphosphorane and deprotection gave the 2'(or 3')-deoxy-2'(or 3')-methyleneadenosines, respectively. Enzymatic deamination afforded the 2'(or 3')-deoxy-2'(or 3')-methyleneinosines. Treatment of 2'-O-(tert-butyldimethylsilyl)-3'-deoxy-3'-methylene-5'-O-tosyladenosine (14) with sodium 2-methyl-2-butoxide and deprotection gave 9-(3,5-dideoxy-3-methylene-beta-D-glycero-pent-4-enofuranosyl)adenine (20). Analogous treatment of a protected 2',5'-dideoxy-5'-iodo-2'-methyleneadenosine derivative gave 9-(2,5-dideoxy-2-methylene-beta-D-glycero-pent-4-enofuranosyl)adenine (22). Biochemical aspects of the putative mechanism-based inhibition of S-adenosyl-L-homocysteine hydrolase and ribonucleotide reductase by these compounds are discussed.
