Abstract
Preparation of dimethyl malonyl-substituted indolo[2,3 -a]quinolizidine der ivative (9), which is a potential synthon in the antirhine (1) series, has been studied. Routes passing through intermediates (22) or (26) are superio r to the route passing via intermediate (7), earlier preconized for that pu rpose.
