Abstract
Interaction of benzil in methanol with 3-aza-1,5-diaminopentane in the presence of HgCl2 yields the title compound, ,8a-hexahydro-8,8a-diphe nylimidazo[1,2-a]pyrazine. The molecule consists of a bicyclic system containing five- and six-membered heterocycles which are joined at C(6 ) and N(2). C(6) is a chiral centre and N(2) has distorted tetrahedral geometry around it. The molecule is puckered at the C(6)-N(2) bond.
