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.

摘要:Penicillins and cephalosporins can be synthesized by the action of an acylase on a penicillin or cephalosporin nucleus amine as substrate and an ester (I) of the following formula as the acyl source: (I) (wherein RCO is an acyl group in penicillin or cephalosporin side chains; X is a hydrogen atom, lower alkyl group or hydroxy-lower alkyl group; Y is a hydrogen atom or a lower alkyl group; and n is a positive integer). The novel acyl source (I) is also disclosed.

摘要:The present invention provides a method for synthesizing 1-(acyloxy)-alkyl derivatives from 1-acyl-alkyl derivatives, which typically proceeds stereospecifically, in high yield, does not require the use of activated intermediates and/or toxic compounds and is readily amendable to scale-up. The current invention also provides 1-acyl-alkyl derivatives of known drug components and methods for synthesizing these 1-acyl-alkyl derivatives.

摘要:The compounds of the formula (II):n and salts and esters thereof wherein the hydroxyl group occupies position 2 or 4 R 1 and R 2 may be the same or different and represent hydrogen, halogen, hydroxy, lower alkyl, cyclopentyl, cyclohexyl, lower alkoxy or R, and R 2 when an adjacent carbon atoms may together represent a 1,4-buta-1,3-dienylene group or a polymethylene group containing from 3 to 5 carbon atoms; have been found to be β-lactam antibiotics and synergists with penicillins and cephalosporins. Their preparation and use is described. The synthesis of intermediates useful in their preparation is also described.
