Stereocontrolled access to orthogonally protected anti,anti-4- aminopiperidine-3,5-diols through chemoselective reduction of enantiopure β-lactam cyanohydrins

(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
