The process development and large scalesynthesis for the β-hydroxyamino amide 1 is described. The route evolved from a multistep sequence utilizing a classical resolution to a two-step enantioselective process involving an enzyme-catalyzed aldol reaction and a direct amidation of a carboxylic acid. By utilizing a silicon-mediated direct amidation strategy, the route was devoid of protecting and deprotecting
