convergent method has been developed to construct a N-(dialkylamino)azacyclic system as a tetrasubstituted hydrazine via reductive alkylation of the corresponding hydrazone using sodium triacyloxyborohydride [NaBH(OCOR)3], which is tolerant of various substituents (e.g., phenol, conjugated olefin, amide, and thioamide) on the substrate and useful for organization of the N-aminoazacycle array.
已开发出一种新的高效且收敛的方法,该方法可通过使用三酰氧基硼氢化钠[NaBH(OCOR)3 ]对相应的re进行还原性烷基化,将N-(二烷基氨基)氮杂环状体系构建为四取代肼,该方法可耐受各种取代基(例如底物上的苯酚,共轭烯烃,酰胺和硫代酰胺),可用于组织N-氨基氮杂环化合物阵列。
