Syntheses of Enantiopure Bicyclic Oxazolidines Using Pd(II) Catalysts

Significance

Bicyclic oxazolidines are important intermediates in synthetic chemistry serving, for example, as valuable building blocks for nitrogen-containing heterocycles that belong to a class of biologically active compounds. Building on previous studies of the diastereoselective synthesis of various β-amino alcohols, the authors report herein a new palladium(II)-catalyzed cyclization of chiral unsaturated β-amino alcohols to afford enantiopure bicyclic oxazolidines with total regio- and stereocontrol.
