Phenylsilane → Fmoc-Dap-OH

Participants

Reaction Steps

A mixture of N-[(9H-fluoren-9-ylmethoxy)carbonyl]-3-[(2-propenyloxy)carbonyl]amino-L-alanine resin (Example 64; 2 g), tetrakis(triphenylphosphine)palladium(0) (509 mg, 0.45 mmol), and phenylsilane (21.9 mmol) in dichloromethane (20 mL) was shaken for 35 min. The resin was washed with dichloromethane and methanol, then vortexed with dimethylformamide/water (1:1) at room temperature for 10 min, and washed again with dichloromethane and methanol to give 3-amino-N-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-alanine on Wang resin.
