The present invention relates to substituted benzopyran derivatives, stereoisomers, and pharmaceutical acceptable salts thereof useful as Estrogen Receptor beta agonists for treating Estrogen Receptor beta mediated diseases such as benign prostatic hyperplasia.
A process for preparing a cholesteric liquid crystal copolyester consisting essentially of structural units represented by the following formula (A), (B), (C) and (D):
which is optically active characterized in that a polyethylene terephthalate oligomer having a (B)/(A) mole ratio in the range of 1.1 to 1.8, p-acetoxybenzoic acid and 3-methyladipic acid are reacted to prepare the final chloesteric liquid crystal copolyester having an inherent viscosity of at least 0.4 dl/g.
