A group of transition-metal catalyzed hydrogen moving reactions, encompassing hydrogen autotransfer (HAT; also called borrowing hydrogen, BH), dehydrogenative condensation (DHC) and alkene isomerization, displays high atom economy and relies on widely ava

3-(3-hydroxyphenyl)-2-butanone (obtained in 3 steps from 3-bromophenol and 3-chloro-2-butanone) was ketalised with ethylene glycol and protected at the phenolic OH as the methoxymethyl ether.The intermediate diacetal thus obtained underwent hydrogen-metal exchange with n-butyllithium; the metallated intermediate, after carbonation, methanolysis of acetal groups and elimination of methanol, regioselectively afforded the title compound (8-hydroxy-3,4-dimethylisocoumarin).

A series of 1--1,2,3,6-tetrahydropyridines were prepared by the reaction between 1-(1-cyanocyclohexyl)-1,2,3,6-tetrahydropyridine (1) and an appropriately substituted Grignard reagent.The resulting compounds were tested for their phencyc
