A CONVERGENT SCHEME FOR THE STEREOSELECTIVE SYNTHESIS OF 3'-NOR-1-OXACEPHEMS
Haebich, D.,Hartwig, W.
, p. 3667 - 3676 (2007/10/02)
A convergent approach to the construction of the 3-hydroxy-oxacephems 1, valuable intermediates for the synthesis of 3'-nor-1-oxacephems, is presented.The key step utilizes the Lewis acid catalyzed stereoselective ring-opening of the oxazoline 2 by an app
