ABSTRACT:
Methods of synthesizing pure enantiomers of acylanalides such as Casodex® (bicalutamide) and its derivatives utilizing a compound having a ring structure that, when opened, provides a substituent having the structure of Formula I:whereinR1is alkyl or haloalkyl having up to 4 carbons;R2is alkyl having up to 6 carbon atoms; andR3is CH2OR4where R4is hydrogen or benzyl, C(O)CH3, or C(O)OR5where R5is hydrogen or alkyl;are disclosed.
