Asymmetric Synthesis of Functionalized Bicyclic β-Amino Alcohols by Cascade Hydrometallation-Cyclization-Reduction of Glycinyl-Substituted Alkenylsulfoximines - Application to the Synthesis of an Aggrecanase Inhibitor Mimic
sulfoximine-substituted β-amino alcohols with formation of the corresponding amino-substituted alkenylsulfoximine and allylic amine was demonstrated. An enantio- and diastereopure protected aggrecanase inhibitormimic was synthesized in high yield starting from the sulfoximine-substituted bicyclic β-amino alcohol with a bicyclo[4.3.0]nonane skeleton and (R)-2-(3-benzyloxy)benzyl-4-tert-butoxy-4-oxobutanoic acid
