A new synthetic method for chiral oxazolines has been developed by NI unit
transfer to olefins using a chiral nitridomanganese complex. When trans-dis
ubstituted styrenes were treated with chiral complex I in the presence of a
n acid chloride. oxazolines were obtained with high enantioselectivities (u
p to 92% ee). Furthermore. the produced oxazolines could be easily converte
d into beta -amino alcohols, which are ephedrine derivatives, (C) 2001 Else
