An enantioselective cyclopropanation reaction of N-substituted 2-pyridones with diazo compounds has been realized by using a chiral rhodium complex as the catalyst, and the corresponding chiral cyclopropanes could be formed in good yields with high enantioselectivities. Moreover, using acceptor-acceptor dimethyl 2-diazomalonate as the carbene precursor, a novel 1,4-rearrangement of a Boc group from N to C has also been discovered under rhodium catalysis.

Alkyl 2-pyridyl carbonates 3 or mixtures of 3 and the isomeric N-(alkoxycarbonyl)-2-pyridones 3' are useful for the introduction of urethane protective groups into amino acids.The N-protected amino acids 7 - 10 react with 2(1H)-pyridone (1a) using the carbodiimide method to yield 2-pyridyl active esters 11, which easily undergo coupling reactions with amino acid esters 12 with elimination of 1a to give peptides 13 in good yields as well as high optical purities.
