GA21381
Diphenyldiazomethane resin (200-400 mesh, 0·7-1·3 mmol/g)
Diphenyldiazomethane was used industrially for producing benzhydryl esters (diphenylmethyl esters) of β-lactam antibiotics· This "polymeric diphenyldiazomethane" readily reacts with carboxylic acids, e·g· Fmoc-amino acids, which need not to be activated· Products can be cleaved from this very acid-sensitive resin derivative with 1-5 % TFA in dichloromethane·Fmoc-α-amino alcohols can be anchored to PDDM in the presence of BF? etherate· As the resulting benzhydryl ethers can be cleaved with 1% TFA/DCM, fully protected peptide alcohols can be obtained
