General and Efficient Approaches to Fused [l,2-a]Pyrroles and [1,2-a]Indoles

2-[(Benzotriazol-l-yl)methyl]pyrroles 4a-c, and 15a,b and -indoles 23, prepared as previously reported,1-2 were converted into the corresponding fused [1,2-a]pyrroles 8a-c, and 18a,b and fused [1,2-a]indoles 25, 27 by intramolecular cyclizations; the form
