ChemInform Abstract
The title compound (IX) is synthesized via its 3,3′-bis-(acetyl) derivative (VIII) by ring closure reaction of the precursor (VI) in refluxing acetic anhydride. This route is first tested by the synthesis of the benzyl indolizine (XII). The latter can be oxidatively dimerized to the 3,3′-bis(indolizine) (XIII) which forms a perfectly reversible two step redox system with KSEM = 4.7×105.
