The pinacol of ligands: The (R)-DTBM-Segphos coordinated copper(I) complex was found to be very effective for the asymmetric hydroboration of β-substituted styrene derivatives with pinacolborane (see scheme; DTBM=3,5-di-tert-butyl-4-methoxyphenyl). This new method affords benzylic pinacol boronate esters with excellent levels of regio- and enantioselectivity (>99 %).
CONFORMATIONAL ANALYSIS OF AMPHETAMINE IN SOLUTION BASED ON UNAMBIGUOUS ASSIGNMENT OF THE DIASTEREOTOPIC BENZYLIC PROTONS IN THE (1)H NMR SPECTRA

The erythro- and threo-amphetamine-β-d diastereomers were synthesized and used for the unambiguous assignment of the diastereotopic benzylic protons and the mesurement of vicinal (1)H-(1)H coupling constants which were used to determine the distribution of rotamers around the central Cα-Cβ bond in the side chain.
