erythro- and threo-ss-Amino boranes Mes2BCHMeCHPh-NHPh were synthesized by the reaction of Mes2BCHMeLi with N-benzylideneaniline. The stereochemistry was determined by chemical derivation into the corresponding cyclic carbamates via ss-amino alcohols. Their thermolysis gave a mixture of the corresponding (E)-enamine and its tautomer, (E)-imine, in sharp contrast to that of ss-hydroxy boranes giving the olefins.
Ti(NMe2)4-catalyzed Markovnikov hydroamination of alkynes in the presence of N-heterocyclic carbenes and LiN(SiMe3)2

Intermolecular hydroamination of alkynes catalyzed by Ti(NMe2)4 was much improved with N-heterocyclic carbenes and LiN(SiMe3)2, by which high Markovnikov selectivity was attained for the coupling of nearly all a
S-chiral sulfinamides as highly enantioselective organocatalysts

, p. 5913 - 5915 (2007/10/03)
(Diagram presented) Easily accessible chiral sulfinamide 2 has been developed as the first highly efficient and enantioselective organocatalyst relying solely on a chiral sulfur center for stereochemical induction. In the presence of 20 mol % of 2, a broa
