Abstract

Expeditious Synthesis of Dihydrobenzo-[Z,Ib : 3,4-b']-, [1,2-b : 5,4-b'], and [1,2-b : 4,5-b']-dipyrroles ... A. Berlin, S. Bradamante, R. Ferraccioli, G. A. Pagani, and F. Sannicolo Dipartimento di Chimica Organica e lndustriale dell'Universita, and Centro CNR Speciali Sistemi Organic;, Via C. Golgi 19, 20133 Milano, Italy ... A simple, high-yield, two-step synthesis of the title compounds (1)-(3) is described, based on the catalytic reduction of the bis-enamines (4)-(6), in turn ...
