Efficient Entry into 2-Substituted Tetrahydroquinoline Systems through Alkylative Ring Expansion: Stereoselective Formal Synthesis of (±)-Martinellic Acid
new efficient synthesis of 2-substituted tetrahydroquinolines has been achieved by the domino reaction of N-indanyl(methoxy)amines, which consists of three types of reactions: elimination of an alcohol, the rearrangement of an aryl group, and the addition of an organolithium or magnesium reagent. The synthetic utility of this approach is demonstrated by the stereoselective formal synthesis of (±)- martinellic
A room-temperature and one-pot synthesis of ε-CF3-substituted amides via the copper-catalyzed trifluoromethylation of alkenes with redox-neutral remote amidation of aldehydes is described. This reaction is featured by an unprecedented 1,5-H atom abstraction from aldehydic C–H bonds by α-CF3-alkyl radicals resulting from the radical trifluoromethylation of alkenes, thus enabling a new possibility of
We report the first example of the construction of chiral 2,3-benzodiazepine compounds which are of biologic and pharmaceutical relevance by asymmetriccatalysis. Catalyzed by a thiazolium-derived carbene and a palladium-chiral bidentate phosphine complex in sequence, one-pot reaction between 1-(2-(2-nitrovinyl)aryl)allyl esters 1 with azodicarboxylates 2 took place efficiently at ambient temperature
