Concise Synthesis of 3-(Aminomethyl)pyrrolizidines via an In(OTf)(3)-Mediated Ring Rearrangement of 2-[2-(1-Pyrrolin-2-yl)alkyl]aziridines
In this study, an efficient ring rearrangement of 2-[2-(1-pyrrolin-2-yl)alkyl]aziridines, prepared from 2-(bromomethyl) aziridines, toward novel trans-and cis-3-aminomethyl-substituted pyrrolizidines was developed. To that end, addition of In(OTf)(3) as an appropriate Lewis acid catalyst resulted in the formation of intermediate pyrrolizidinium salts via regioselective aziridine ring opening, which were then trapped by a hydride or cyanide nucleophile. Column chromatographic purification allowed the isolation of the major trans-isomers, exclusively.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.
