Notes and discussion. This procedure is used to form the kinetic P-trichloroace-timidate product in the imidation reaction and is based on the method reported by Schmidt et al. [16]. It utilizes a relatively mild base (potassium carbonate) which is essentially unable to catalyse the reverse imidation reaction. Hence equilibration between a- and P-imidate products is not possible and the kinetic product dominates. It is of note, however, that reactions of this type must be monitored carefully if the yield of the kinetic product is to be maximised. The P-trichloroacetimidate product could be used under SN2-like glycosylation conditions to provide access to a-glycosides [25]. [Pg.153]
