Abstract [3,3] Sigmatropic rearrangement of unsymmetrically substituted 1,4-but-2-ynes exhibit preference for rearrangement on the aryloxy prop-2-ynyl moiety to N-methyl-N-pyrimidinyl amino prop-2-ynyl moiety in case of 5-substituted uracils (la-f).
摘要 [3,3] 不对称取代的 1,4-but-2-yne 的 Sigmatropic 重排表现出优先将芳氧基丙-2-炔基部分重排为 N-甲基-N-嘧啶基氨基丙-2-炔基部分,以防万一5-取代尿嘧啶 (la-f)。
