The palladium‐catalyzed aminocarbonylation of aliphaticalkenes is presented for the first time without the need for external CO pressure. N,N‐dimethylformamide (DMF) is used as an in situsource of both the required carbon monoxide and the amine substrate. The applied palladium catalytic system is well‐known for a number of carbonylation reactions, including those with CO surrogates and tandem isomerizing

The present invention relates to a novel class of 1,3-benzoxazol-2(3H)-ones and their use as a medicament, preferably as a dermatologic agent, and as a cosmetic. These novel compounds are particularly useful in treating and/or preventing inflammation, irritation, itching, pruritus, pain, oedema and/or pro-allergic or allergic conditions in a patient. Usually they are topically applied to the skin or mucosa in the form of a pharmaceutical or cosmetic composition comprising the compound and a pharmaceutically and/or cosmetically acceptable carrier.
Indole and indoline derivatives of the formula:
wherein indicates a double bond or a single bond between carbon atoms, R1 represents an alkyl group containing 1 to 6 carbon atoms (which may be substituted by one or more than one of the same type of substituents selected from the hydroxy group, alkenyl groups containing 2 to 5 carbon atoms, and alkanoyloxy groups containing 2 to 7 carbon atoms) or a hydrogen atom, and one of the symbols R2 represents an alkyl group containing 6 to 24 carbon atoms and the other symbol R2 represents an alkyl group containing 1 to 24 carbon atoms, or a hydrogen atom, and R3 reptesents an alkyl group containing 1 to 6 carbon atoms or a hydrogen atom, are new compounds possessing useful pharmacological properties. They are of use in the treatment of diabetes mellitus, hyperlipoproteinaemic states, of atherosclerosis, and of associated disorders. Pharmaceutical compositions containing the compounds are described and so are numerous processes for oreparing the compounds.
