标题 :Methods for synthesis of acyloxyalkyl compounds
发明人:BHAT LAXMINARAYAN; GALLOP MARK A
权利人:XENOPORT INC
摘要:Disclosed herein are methods for synthesizing 1-(acyloxy)-alkyl prodrug derivatives of drugs through oxidation of 1-acyl-alkyl derivatives of drugs under anhydrous reaction conditions. The methods typically proceed stereospecifically, in high yield, do not require the use of activated intermediates and/or toxic compounds and are readily amenable to scale-up.
