A new method for the synthesis of 1,2-syn-vic amino alcohols (with double inversion of configuration) from vinyl epoxides, by the amination of a π-allyl palladium-borate complex generated by using Pd(0) and phenyl-o-phenylene borate (a double activation technique), is reported. Further, this new method with broad functional group compatibility was extended to a one-pot/two-step synthesis of chiral benzoxazine and quinoxaline derivatives.
