We report herein a Pd(II)/bis-sulfoxide-catalyzed intramolecular allylic C-H acetoxylation of aryl allyl ether, amine, and amino acids with the retention of a labile allyl moiety. Mechanistically, the reaction proceeds through a distinct double-bond isomerization from the allylic to the vinylic position followed by intramolecular carboxypalladation and the β-hydride elimination pathway. For the first time, C-H oxidation of N-allyl-protected amino acids to furnish five-membered heterocycles through 1,3-syn-addition is established with excellent diastereoselectivity.

We prepared a series of N-aryl isoxazolecarboxamide, N-isoxazolylbenzamide compounds and derivatives and studied their anticonvulsant action in MES and MMS tests. Some of these reveal considerable activity, especially with respect to MES test. The disubstitution in the 2.6-position on the phenyl ring by two methyl groups would appear to be of primary importance for the activity. The amide bridge between the phenyl and isoxazolic rings, whether of the anilide or benzamide type, seems to show similar anticonvulsant behavior. We have selected the derivatives 8 (N-(2.6-dimethylphenyl)-5-methyl-3-isoxazolecarboxamide, 12 (N-(2.6-dimethylphenyl)-5-hydroxymethyl-3-isoxazolecarboxamide) and 51 (N-(5-methyl-3-isoxazolyl)-2.6-dimethylbenzamide) which are presently being studied in more extended pharmacological tests.
