Appeal No. 96-0724
Application No. 07/817,232
The subject matter on appeal, in one aspect, is directed
to a process for the selective preparation of certain R-
enantioners or S-enantioners [halophenyl acylates (esters)] of
the formula set forth in appealed claim 1 by treating certain
substrates (starting reactants) of the formula set forth in
appealed claim 1 with an acylating agent and certain
microorganisms or enzymes obtained therefrom also as defined
by appealed claim 1. In a second aspect of the invention, the
acylates obtained through the reaction of the process of
appealed claim 1 are hydrolyzed to selectively produce certain
R-enantioners or S-enantioners
(halophenyl alcohols) by a reaction as set forth in appealed
claim 2. Products obtained by the reactions are said to be
useful as antipsychotic agents or as intermediates in the
preparation thereof (specification, page 4, lines 23-26).
Copies of representative appealed claims 1 and 2 are
reproduced in an attached appendix.
