We describe Pd-mediated one-step synthesis of 11-substituted 6H-isoindolo[2,1-a]indol-6-ones via a sequential intramolecular Heck reaction of the corresponding dihalo N-allyl substituted N-arylbenzamide derivatives. Several of these compounds showed promi

5,11-Dihydro-6H-pyrido[2,3-b][1,4]benzodiazepin-6-one (1), a basic intermediate in the preparation of 11-α-aminoacetyl derivatives with important biological activities, has been obtained by a three-step synthesis starting from easily available isatoic anhydride and anhydro ornithine. Some model cyclisation reactions leading to 5-member ring derivatives 10 and 12 instead of 7-member ring analogues of 1, are reported. Easy transformations of the tetrahydro congener of 1, i.e. compound 4 into 19, which actually represents a tetrahedral intermediate in the transformation of 5 into 4, is noticed. Further rearrangement of 19 into spiro compounds 20, and return of the latter into 5 is described.
