Diastereoselective syntheses
O 0031
Diastereoselective Addition of Organolithiums to 1,3-Oxazolidines Complexed
Aluminum Tris(2,6-diphenylphenoxide) (ATPH). — Addition of organolithi25- 031 with
ums to readily available oxazolidines (I) and (V) complexed with ATPH furnishes
β-amino alcohols with good yields and diastereoselectivities. The configuration of the
new stereogenic center is mentioned to be opposite to that obtained by the analogous
reaction using Grignard reagents except for substrate (Ib). — (YAMAUCHI*, T.;
