Diastereoselective Synthesis of 2,3-cis-Alkyl-3-oxygenated Piperidine Derivatives by Titanium Mediated Intramolecular Cyclization of a-Aminoacetal-allylsilane System
form a cyclichemiacetal, was identified as calpain inhibitors. The placement of isobutyl group at the 2-position of the 3-morpholinone was the most effective modification for inhibiting micro- and m-calpains. Substitutions of benzyl at the 5-position in the S-configuration had virtually no effect on inhibitory activity. Several compounds showed appreciable selectivity for calpains over cathepsin B. NMR
