Wei, Duo published the artcileIron-catalyzed hydrosilylation of diacids in the presence of amines: a new route to cyclic amines, SDS of cas: 627-93-0, the publication is ChemCatChem (2020), 12(21), 5449-5455, database is CAplus.
Herein, a novel chemoselective strategy for building N-substituted cyclic amines I (n = 1, 2, 3; R = H, 4-Me; R1 = cyclohexyl, 1-(naphthalen-1-yl)ethyl, 2H-1,3-benzodioxol-5-yl, etc.) and 2-(4-methoxyphenyl)-2,3,3a,4,7,7a-hexahydro-1H-isoindole via iron catalyzed one-pot hydrosilylation starting from readily available dicarboxylic acids e.g., pentanedioic acid and amines R1NH2, with hydrosilanes as the hydride sources was presented. The described methodol. allows the preparation of a wide range of N-alkylated and arylated cyclic amine derivatives I (including pharmaceuticals Fenpiprane and Prozapine) in moderate to excellent yields, starting from inexpensive succinic, glutaric, and adipic acids with di-Me carbonate as a green solvent.
