Novel chemistry of α-tosyloxy ketones: Applications to the solution- and solid-phase synthesis of privileged heterocycle and enediyne libraries

Nicolaou,Montagnon,Ulven,Baran,Zhong,Sarabiat

, p. 5718 - 5728 (2007/10/03)

New synthetic technologies for the preparation and elaboration of α-tosyloxy ketones in solution and on solid-phase are described. Both olefins and ketones serve as precursors to these relatively stable chemical entities: olefins via a novel one-pot epoxi
