N-Hydroxyamidoximes, N-aminoamidoximes, and hydrazidines belong to a class of compounds with the general formula RC═NX(NHY) where X = OH or NH2, Y = OH or NH2, and R is a linear side chain, carbocycle residue, or heterocycle ...

An efficient protocol for the catalytic asymmetric synthesis of new dibenzo[b,f][1,4]-oxazepine-fused 1,2-dihydropyridines (DHPs) has been described under metal-free conditions. This reaction proceeds through proline-catalyzed ...

Diphenylprolinol silyl ether was found to be an effective organocatalyst for promoting the asymmetric, catalytic, intramolecular [6 + 2] cycloaddition reactions of fulvenes substituted at the exocyclic 6-position with a ...
