1,3-Di-N-substituted uracil and its derivatives have been reduced with lithium-tri-sec-butyl borohydride to the corresponding 5,6-dihydro compounds in excellent yields. Alkylation of 5-position of uracil is also very conveniently accomplished.
用三仲丁基硼氢化锂将1,3-二-N-取代的尿嘧啶及其衍生物还原成相应的5,6-二氢化合物,产率极高。尿嘧啶5-位的烷基化也很方便地完成。
