WebThe Dde group is utilized when a lysine residue is to be selectively modified, as in a cyclization or a dye labeling. The Dde group is removed with hydrazine which does not affect t-butyl based protection groups. 19 The deprotection byproduct is a strong UV absorption and the deprotection reaction can be monitored photometrically.
