Abstract

Initial thinking dictated that the desired aromatic compounds, 18-23, could be prepared by extensions of known reactions. 6 However, several experimental observations made during the course of our investigation proved to be far from routine. The two methods considered applicable for the preparation of ketones, 12-17, which could be cyclized to the desired aromatic products, 18-23, are illustrated in Chart I. Method A involves the reaction of an ...
