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

10.1021/jo0161429

The study presents a Pd(II)-catalyzed cyclization method for the highly regio- and diastereoselective synthesis of optically active 4-vinyl-2-oxazolidinones from difunctional allylic N-tosylcarbamates, which serves as a convenient approach for the total synthesis of 1,4-dideoxy-1,4-imino-L-xylitol. Key chemicals used in the study include Pd(OAc)2 as the catalyst, LiBr or other halide ions as essential additives, and various homochiral alcohols as substrates. These reagents and substrates are crucial for the cyclization reaction, which involves aminopalladation of alkene and β-heteroatom elimination to regenerate Pd(II) species, yielding the desired 4-vinyl-2-oxazolidinones with high optical activity. The study also explores the mechanism of the reaction and demonstrates the utility of the method through the synthesis of 1,4-dideoxy-1,4-imino-L-xylitol, a potential glycosidase inhibitor.
