The absolute rate constants for the reaction of different aryl radicals with 2-naphthoxide anion were determined using an indirect method, a competition of the coupling reaction with the H-atom abstraction. We here show that the radical-ambident nucleophi

Optically active α-amino alcohols have been synthesized by Sharpless' method with (-)-10,11-dihydroquinine 2 and (R)-(-)-pantolactone 8 as chiral inducers.Five secondary (dl) alcohols : 3,4,5,6,7 and (dl) 2-hydroxyheptahelicene 1 have also been used to prepare the intermediate diastereomeric (dl) α-hydroxy carbamates 9.The highest inductions were obtained with (-)-10,11-dihydroquinine and (E)-stilbene (e.e. >/=98percent and with (dl) 2-hydroxyheptahelicene and (E)-stilbene (d.e. >/=98percent).
