nucleosides with olefinic 2′-modifications were prepared; 2′-C-methylene, 2′-C-(propen-1-yl), 2′-C-allyl and 2′-O-allyl uridines, respectively. These were incorporated into dinucleotides with allyl phosphate or vinyl phosphonate linkages. Hence, six different dinucleotides were studied as substrates for RCM reactions, and from four of these, cyclic dinucleotides with connections between 2′-C and phosphorus
制备了具有烯烃2'-修饰的四个不同的核苷。2′- C-亚甲基,2′ - C-(丙烯-1-基),2′- C-烯丙基和2′- O-烯丙基尿苷。将它们掺入具有烯丙基磷酸酯或乙烯基膦酸酯键的二核苷酸中。因此,研究了六种不同的二核苷酸作为RCM反应的底物,并从其中的四个中获得了2'-C和3-6个原子的磷之间有连接的环状二核苷酸。
