One-pot synthesis of α-methyl ketones starting from 1,3-diaryl propenols or 1-aryl propenols and methanol as a C1 source is demonstrated. This one-pot isomerization-methylation is catalyzed by commercially available Pd(OAc)2 with H2O as the only by-product. Mechanistic studies and deuterium labelling experiments indicate the involvement of isomerization of allyl alcohol followed by methylation through a hydrogen-borrowing pathway in these isomerization-methylation reactions.

Prochiral racemic allylic alcohols are converted to enantioenriched chiral alcohols bearing adjacent stereocenters catalyzed by a diamine diphosphine Ru complex in the presence of tBuOK. The protocol features a broad substrate scope (56 examples) and high
Synthesis of polysubstituted quinolines via transition-metal-free oxidative cycloisomerization of o -cinnamylanilines

An efficient synthesis of 2-aryl 4-substituted quinolines from stable and readily available o-cinnamylanilines, prepared from anilines and cinnamylalcohols, has been developed. The reaction occurred via a regioselective 6-endo-trig intramolecular oxidative cyclization using KOtBu as a mediator and DMSO as an oxidant at rt. The reaction showed a broad substrate scope with good to excellent yields.
Hydroxy-Directed Hydroaluminations: A Stereoselective Approach to Cycloalkanols From β-Aryl Enones.

Various aryl substituted enones are reduced using lithium aluminum hydride to afford sterioselectively trans substituted alkanols.Mechanistic studies demonstrate 1,2-addition followed by hydroxy-directed hydroalumination of the conjugated styryl unit.
