Solid-phase synthesis of aspartic peptidase inhibitors: 3-alkoxy-4-aryl piperidines

[reaction: see text]. The 3-alkoxy-4-aryl piperidines are non-peptide peptidomimetic inhibitors of several aspartic peptidases. The solid-phase functionalization of 3,4-disubstituted piperidine scaffolds using a traceless linker strategy is described. Synthesis of diverse analogues based on this scaffold provides the potential to generate selective inhibitors of this important class of peptidase.
