Different families of new amino compounds were efficiently synthesized, through optimized sequential processes, involving rhodium catalyzed hydroformylation as the key step. The selection of appropriate hydroformylation catalytic systems and reaction conditions allowed obtaining aldehydes derived from several n-alkyl olefins, cholest-4-ene and 3-vinyl-1H-indole, which were subsequently transformed
通过优化的连续过程有效地合成了不同家族的新氨基化合物,其中涉及铑催化的加氢甲酰化为关键步骤。选择合适的加氢甲酰化催化体系和反应条件可以得到衍生自几种正烷基烯烃,胆甾烯-4烯和3-乙烯基-1 H-吲哚的醛,随后将它们一锅转化为α-氨基酸通过加氢甲酰化/的Strecker反应,并在叔胺经由hydroaminomethylation,具有优良的产率。
