the job: 1,6‐Difunctionalized alkyl units, which are traditionally hard to access, have been successfully obtained through a reductive cross‐coupling of activatedalkenes catalyzed by TiIII. A plausible reaction mechanism that proceeds through redox umpolung of the enone is briefly discussed (see scheme, Cp=cyclopentadiene).

bearing (−)-8-phenylmenthol as a chiral auxiliary with aliphaticaldehydes is realized under photolysis. This work represent the first example of diastereoselective addition of acyl radicals to olefins to afford chiral ketones in a highly stereoselective fashion. The reaction is initiated by the photolysis of hypervalent iodine(III) catalyst under mild and metal-free conditions. The synthetic potential

An air and moisturestable C3‐symmetric titanium(IV) triflate, supported by a tripodal amine‐(tris‐phenolate) ligand, has been synthesized and characterized by X‐ray crystallography and shown to be a good Lewisacidcatalyst for a range of aza‐Diels–Alder, Diels–Alder, syn aldol, allylation, and alkylation reactions.
