The HgCl2-promoted guanylation reaction was studied with various substituted thiourea starting materials and the scope and limitations are presented. The process was found to be effective with thioureas containing at least one N-conjugated substituent. Such activating groups include N-carbonyl- (acyl, alkoxycarbonyl, carbamoyl, etc.), N-cyano-, N-sulfonyl-, and N-aryl- substituents.
用各种取代的硫脲原料对HgCl 2促进的鸟苷化反应进行了研究,并提出了范围和局限性。发现该方法对于含有至少一个N-共轭取代基的硫脲是有效的。这样的活化基团包括N-羰基-(酰基,烷氧基羰基,氨基甲酰基等),N-氰基-,N-磺酰基-和N-芳基-取代基。
