Synthesis and reactions of 2-methyl-3-methylamino-2-azabicyclo[3.2.1]-oct-6-ene and its valence isomer
Abstract
2-Methyl-3-methylamino-2-azabicyclo[3.2.1]oct-6-ene (4) has been prepared and shown to coexist with N-methyl-4-(2-methyliminoethyl)cyclopent-2-enylamine (3). This material behaves as the gem-diamine (4) on catalytic reduction and as the imine (3) on reduction with metal hydrides. A useful method of synthesising cis-3,5-disubstituted cyclopentenes is reported.
