On the Mechanism of the Aziridine Synthesis from 2-Azido-alcohols and Triphenylphosphine
Poechlauer, Peter,Mueller, Ernst Peter,Peringer, Paul
, p. 1238 - 1247 (1984)
The reaction of selected 2-azido-alcohols, their pivalates, and methanesulfonates with triphenylphosphine was investigated.It is shown that the formation of aziridines from 2-azido-alcohols proceeds via 1,3,2λ5-oxazaphospholidines.Furthermore, the first synthesis of the unsubstituted acenaphthene-1,2-imine is described.

A sequential one-pot Cu-catalyzed asymmetric Henry reaction and iodocyclization is disclosed. The transformation provides efficient access to biologically and synthetically useful 2,2,5-trisubstituted tetrahydrofuran derivatives. The combination of Cu(OAc)2·H2O with a novel chiral sulfoxide-Schiff base hybrid ligand under mild reaction conditions tolerates a wide range of 4-substituted γ,δ-unsaturated aldehydes, and the subsequent iodocyclization furnishes the corresponding products in generally high yields with excellent enantioselectivities. The products can be easily converted into amines with excellent diastereo- and enantioselectivities.

A new class of chiral sulfoxide-Schiff base ligands has been developed by the rational combination of two privileged chiral backbones. These sulfoxide-Schiff base ligands were found to be highly efficient for Cu-catalyzed asymmetric Henry reactions (up to
