Asymmetric radical azidation for the synthesis of chiral alkylazides remains a tremendous challenge in organic synthesis. We report here an unprecedented highly enantioselective radical azidation of acrylamides catalyzed by 1 mol % of a copper catalyst. The substrates were converted to the corresponding alkylazides in high yield with good-to-excellent enantioselectivity. Notably, employing an anionic cyano-bisoxazoline (CN-Box) ligand is crucial to generate a monomeric CuII azide species, rather than a dimeric CuII azide intermediate, for this highly enantioselective radical azidation.

A method is described for the control of nematodes in agricultural crops which comprises applying to the situs of infestation a nematicidal composition containing as active ingredient a compound of the formula STR1 wherein R1 and R2 are hydrogen, lower alkyl, or halogen, X is hydrogen or halogen, n is 1 or 2, Y is hydrogen, lower alkyl, halogen, trifluoromethyl, lower alkoxy, lower alkylthio, and nitro when n is 1, and halogen when n is 2, with the proviso that at least 1 of R1, R2, and X must be halogen. Preparation of active ingredient compounds is described, and nematicidal utility of compositions is exemplified.
