3-Oxa-OPC and 2-fluoro-OPC homologues which do not undergo beta-oxidat
ion were synthesized from esters of odd-numbered OPC homologues by a s
hort-step procedure. The 3-oxa-OPC homologues were synthesized via eth
erification of an alcohol with tert-butyl bromoacetate under phase-tra
nsfer conditions. The 2-fluoro-OPC homologues were synthesized via the
addition of the trichloromethyl anion to an aldehyde and subsequent f
luorination.
