A copper-catalyzed asymmetric O-H insertion of α-di-azophosphonates with alcohols by using chiral spiro bisoxazoline ligandswas developed. The insertion reaction exhibited good yields (upto 89%) with high enantioselectivities (up to 98% ee)and provi

A palladium-catalyzed asymmetric umpolung allylation reaction of imines with allylic alcohols has been developed. In the presence of chiral spiro phosphoramidite ligand 4, the allylation was accomplished with high yields and good enantioselectivities

The asymmetric O—H insertion of α-diazo phosphonates with alcohols in the presence of a catalyst, generated in situ from a Cu(I) precursor, a chiral spiro bisoxazoline ligand and a sodium borate, provides good yields of α-alkoxy phosphonates with
