2-Carbomethoxynorbornene is identified as a more effective transient mediator to promote a Pd(II)-catalyzed meta-C(sp2)-H alkylation of amides with various alkyl iodides as well as arylation with previously incompatible aryl iodides. The use of a tailor-made quinoline ligand is also crucial for this reaction to proceed.

The kinetic resolution of α-acetoxy N-acyl oxazolidinethiones using the chiral, nonracemic O-nucleophilic acyl transfer catalyst 8 is described. The reaction proceeds on a variety of substrates in excellent yields, with s-factors ranging from 17 to 31. Copyright

Oxidation of (+/-)-mandelohydroxamic acid with tetraethylammonium periodate in the presence of (E)-penta-1,3-diene at 0 deg C gave a mixture of 4 racemic cycloadducts of the derived, transient acylnitroso compound (+/-)-2.The 6-methyl 5 and 6 and 3-methyl 7 and 8 pairs of diastereoisomeric dihydro-oxazines were obtained in the ratio 3.0 : 1 : 1.2 :1.2 , respectively.The relative configurations of the racemic cycloadducts 5 and 7 were determined by X-ray crystallography.The relative asymmetric inductions observed for the pairs of regioisomers 5 and 6 and 7 and 8 are briefly discussed.
