Palladium‐catalyzed activation of remote meta‐C−H bonds in arenes containing tethered alcohols was achieved with high regioselectivity by using a nitrile template. Computational studies on the macrocyclic transition state of the regioselectivity‐determining C−H activation steps revealed that both the C‐N‐Ag angles and gauche comformations of phenyl ether play an extremely important role in the meta selectivity

A 1,2,4-oxadiazole derivative is represented by the following general formula (I): ##STR1## wherein R.sup.1 represents a lower alkyl or cycloalkyl group, a lower alkyl group substituted with a halogen atom, a lower alkylamino group or a phenyl group; R.sup.2 represents a hydrogen atom, a lower dialkylamino group, a cyclic alkylamino group, a cyclic amino group having an oxygen or nitrogen atom in the ring, a phenyl group which may be substituted with a halogen atom, a pyridyl group, an imidazolyl group, an alkylimidazolyl group, a benzimidazolyl group or a 2-oxopyrrolidinyl group; and n is 1, 2 or 3. The derivative has excellent monoamine oxidase-inhibitory activity and is effective as a medicine for treating Parkinson's disease.

Sodium tert-butoxide promotes the efficient etherification of alcohols with aryl bromides at room temperature. This simple procedure has a broad substrate scope, providing a practical pathway to arylalkyl ethers in good yields without the addition of any transitionmetal species.
Therapeutics of metastatic or triple-negative breast cancer are still challenging in clinical. Herein we demonstrated the design and optimization of a series of hybrid of 2,4-diaminopyrimidine and arylthiazole derivatives for their anti-proliferative properties against two breast cancer cell lines (MCF-7 as human breast cancer and MDA-MB-231 as triple-negative breast cancer). More importantly, some of those compounds with potent antiproliferative activities also indicated excellent inhibitory activities against MDA-MB-231 cell migration. These results suggested that the new series of hybridation of arylthiazoles and aminopyrimidines could be identified and developed as novel highly potential anticancer agents against the triple-negative breast cancer as well as metastatic one in the future.
