obscure effects influencing the electrophilic nitrosation of activated pyrimidines (Tetrahedron 2007, 63, 5394) was shown to be erroneous. Instead of electrophilic substitution at position 5 of the pyrimidine ring, N-nitrosation of the secondary amino group in the 4-position of the pyrimidine ring took place. Moreover it was shown that the synthetic sequence for the preparation of purines is also incorrect
了一系列的影响激活嘧啶的电亚硝化(意外和模糊效果的报告四面体 2007年,63,5394)被证明是错误的。取代在嘧啶环的5位上进行亲电取代,在嘧啶环的4位上发生仲氨基的N-亚硝化。此外,已经表明,制备嘌呤的合成顺序也是不正确的。
