Diphenylphosphoryl azide (DPPA) mediated one-pot synthesis of Nα-Fmoc/Bsmoc/Boc/Z-protected ureidopeptides and peptidyl ureas as well as phenyl/succinimidyl (Nα-urethane protected) methyl carbamates starting from Nα-protected amino acids is reported. The formation of an azide, its rearrangement and coupling with an amino component is accomplished in a sequence of one-pot operations. The protocol has

The direct condensation of dipeptides with acetone has been found generally useful for the preparation of 2-(2,2,4-trialkyl-5-oxoimidazolidin-1-yl)alkanoic acids. Peptidesynthesisusing these NN′-isopropylidenedipeptides may be conveniently carried out with dicyclohexylcarbodi-imide; such couplings are racemisation-free even in the absence of additives. Subsequent deprotection may be effected by
