(Chemical Equation Presented) The cyanosilylation of enantiopure 4-oxoazetidine-2-carbaldehydes with tert-butyldimethylsilyl cyanide was promoted by either molecular sieves or catalytic amount of sodium carbonate to give O-silylated β-lactam cyanohydrins
Stereoselective allylation of 4-oxoazetidine-2-carbaldehydes. Application to the stereocontrolled synthesis of fused tricyclic β-lactams via intramolecular Diels-Alder reaction of 2-azetidinone-tethered trienes
