Unexpected formation of 5,12-dimethyl-3,7,10,14,15,16-tetraazapentacyclo[7.5.1.12,8.15,16.112,15]octadecane, a novel caged nitrogen heterocycle, and preparation and X-ray crystal structure of its copper(II)chloride complex

Abstract

1,1,1-Tris(aminomethyl)ethane 2 is shown to condense with glyoxal in methanaol, in the absence of metal ions, to give a novel caged nitrogen heterocycle 3 whose structure has been confirmed by spectral data and through X-ray crystallographic analysis of its copper(II) chloride complex 5.
