A simple and efficient protocol for sensing the absolutestereochemistry and enantiomeric excess of chiral monoamines is reported. Preparation of the sample requires a single-step reaction of the 1,1′-(bromomethylene)dinaphthalene (BDN) with the chiral amine. Analysis of the exciton coupled circulardichroism generated from the BDN-derivatized chiral amine sample, along with comparison to conformational

Intermolecular carbon radical addition to the carbon−nitrogen double bond of ketimines was studied. In the study on the reactivity of various aldimines, we found that the aldimine 7 having a phenolic hydroxyl group shows an excellent reactivity toward nucleophilic carbon radicals. A remarkable effect of phenolic hydroxyl group is assumed to be the stabilization of intermediate aminyl radical provided by a

Hofmann rearrangement of carboxamides to carbamates using Oxone as an oxidant can be efficiently catalyzed by iodobenzene. This reaction involves hypervalent iodine species generated in situ from catalytic amount of PhI and Oxone in the presence of 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) in aqueousmethanol solutions. Under these conditions, Hofmann rearrangement of various carboxamides affords corresponding
