Lewis acid catalyst, transforming the well known, but drastic, exchange of the acetyl group of vinyl acetate with pyrimidine and purine derivatives in a very gentle and quick method to obtain a whole set of vinyl nucleobases.
三甲基甲硅烷基三氟甲磺酸盐 (TMSOTf) 再次揭示了其作为路易斯酸催化剂的巨大灵活性,以一种非常温和且快速的方法将乙酸乙烯酯的乙酰基与嘧啶和嘌呤衍生物进行了众所周知但剧烈的交换,从而获得了整套乙烯基核碱基。
