Highly diastereoselective alkylation of the Dellaria oxazinone template with bifunctional electrophiles

Roos, Gregory H. P.,Dastlik, Kim A.

, p. 2197 - 2208 (2007/10/03)

This study investigates the efficiency of alkylation of the Dellaria oxazinone glycinate template with sensitive bifunctional electrophiles. In addition to improved access to the template, triflate/halide bifunctional combinations provided good yields (85-93%) of highly diastereoselective alkylation products.
