of a catalytic amount of NaOH, the selective N-alkylation of various heteroaromatic primary amines is reported. With 1 equiv of NaOH, N1,C5-dialkylation of 4-phenyl-2-aminothiazoles has been investigated. Reaction of in situ generated aldehyde with amine yields the N-alkylated and N1,C5-dialkylated products through hydride ion transformation from alcohol.
据报道,在催化量的NaOH存在下,各种杂芳族伯胺的选择性N-烷基化。用1当量的NaOH,已经研究了4-苯基-2-氨基噻唑的N 1,C 5-二烷基化。原位产生的醛与胺的反应通过从醇中进行的氢化物离子转化产生N-烷基化的产物和N 1,C 5-二烷基化的产物。
