description
PEGylating spacer molecule suitable for standard Click conjugation. In combination with tetrazine linkers it can also be used in copper-free Click conjugations (Diels-Alderreactions).
Propargyloxycarbonyl, commonly abbreviated as Poc or Pryoc, can either be used as alkyne component for standard Click conjugation or in combination withtetrazine linkers in copper-free Diels-Alder type Click reactions. It also has applications as unusual protecting group for amines, hydroxy functions and as esters. All 3 are stable to neat TFA, but can be cleaved at ambient temperature with Co2(CO)8 in TFA:DCM. Deprotection with other transition metals like palladium have also been reported.
