For partial phenylcarbamoylation of the hydroxy-groups of ribonucleosides, dibutyltin oxide--phenyl isocyanate system was found to be surperior to the bis(tributyltin) oxide--phenyl isocyanate system from the standpoint of reaction procedures including isolation of the products; the reaction was proved to occur with similar regioselectivity and to give the corresponding 5'-, 3'-, and 2'-O-phenylcarbamoyl derivatives in good yields, respectively, due to the conditions used.
对于核糖核苷羟基的部分苯基氨基甲酰化反应，从包括产物分离在内的反应步骤来看，发现二丁基氧化锡-苯基异氰酸酯体系优于双（三丁基锡）氧化物-苯基异氰酸酯体系；由于所采用的条件，该反应被证明具有相似的区域选择性，分别以良好的产率得到相应的5'-、3'-和2'-O-苯基氨基甲酰衍生物。
