A novel Pd/sulfoxide catalyzed diastereoselective allylic C-H amination reaction of chiral homoallylic N-tosyl carbamates is reported. Densely oxygenated ∞-olefin substrates with multiple stereogenic centers undergo allylic C-H amination in excellent yiel
Palladium(II)-catalyzed highly regio- and diastereoselective cyclization of difunctional allylic N-tosylcarbamates. A convenient synthesis of optically active 4-vinyl-2-oxazolidinones and total synthesis of 1,4-dideoxy-1,4-imino-L-xylitol

A Pd(II)-catalyzed cyclization of difunctional allylic N-tosyl carbamates in the presence of halide ions was developed with high regio- and diastereoselectivity. The reaction involves aminopalladation of alkene and β-heteroatom elimination to regenerate Pd(II) species. When the readily available homochiral alcohols were used as substrates, highly optically active 4-vinyl-2-oxazolidinones were easily obtained. The utility of this method was exemplified by the convenient synthesis of 1,4-dideoxy-1,4-imino-L-xylitol.
