Abstract

As part of a program for the synthesis of leukocyte recruitment inhibitors (leumedins)'we required substantial quantities of 9H-fluorene-9-acetic acid (3a). While 3a is commercially available, we found the price to be prohibitively high? A number of routes to 3a have been described in the literature.'These include Reformatsky reaction with fluorenone (1), 3b, c alkylation of diethyl malonate with 9-brom0lluorene,~~ alkylation of tluorene with glycolic ...
