The ring-opening of functionalized epoxides with trimethylsilyl azide in the presence of a catalytic amount of Ti(O-i-l%)4 or Al@-i-F?)3 is described. The reaction is stereo8pecific and highly regiospecific, leading generally to the formation of the carbon-azido bond on the less substituted carbon.

This paper reported a new class of diastereomerically pure ortho-methoxydiazaphosphonamide Lewis bases prepared from the corresponding o-hydroxyarylphosphonamides. These bases have been applied to the catalytic asymmetric ring opening of cyclooctene oxide with SiCl 4 . During the last weeks, I discl
