title: Novel hydrazino-carbonyl-amino-methylated polystyrene (HCAM) resin methodology for the synthesis of P1-aldehyde protease inhibitor candidates.
abstract: [structure: see text] A new strategy for the synthesis of peptidyl and peptidomimetic P1-aldehydes 3 on HCAM solid support is described. The appropriate C-terminal aldehyde precursors were prepared and anchored to a resin support via a semicarbazone linkage (HCAM resin). After synthetic elaboration, acidic hydrolysis efficiently delivered C-terminal target aldehydes 3a-h in good overall yields and in excellent purity.
