The invention provides a method of sustained delivery of a lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug by administering to a patient an effective amount of a prodrug compound of the invention wherein upon administration to the patient, release of the parent drug from the prodrug is sustained release. Prodrug compounds suitable for use in the methods of the invention are labile conjugates of parent drugs that are derivatized through carbonyl linked prodrug moieties. The prodrug compounds of the invention can be used to treat any condition for which the lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug is useful as a treatment.

tautomerisation and hydrolysis gave α-hydroxy ketones, ketones, and γ-keto esters in good yield, thereby providing a convenient new acyl-anionequivalent. Reaction of these lithium salts with aldehydes and ketones, followed by elimination provided a new route to azo alkenes.

reagents react with car☐ylic chlorides, in THF between 0 and 10°C, to give the corresponding ketones in highyields. The scope of the reaction is very large; alkyl, alkenyl and aryl magnesium reagents have been used successfully. The selectivity of the reaction allows to prepare various fonctionalized ketones from car☐ylicacid chlorides bearing a functional group (Cl, Br, ester nitrile and even a ketone)
在催化量的氯化锰(3%MnCl 4 Li 2)的存在下,有机镁试剂在0至10°C之间的THF中与羧基氯化物反应,以高收率得到相应的酮。反应范围非常大。烷基,烯基和芳基镁试剂已成功使用。反应的选择性允许从带有官能团(Cl,Br,酯腈甚至是酮)的汽车☐酰氯制备各种功能化的酮。

Organomanganese chloride reagents react with carboxylic acid chlorides, in THF, to give the corresponding ketones in excellent yields. The reaction is of broad scope, it is very interesting from practical and economical point of view since organomanganese chlorides (in THF) are the most stable and cheap organomanganese reagents. With methyl, aryl, alkenyl and s- or t-alkylmanganese chlorides, the acylation
