Description

General description

This orthogonally-protected lysine derivative is based on the hindered Dde variant ivDde. It has very similar chemical properties to Fmoc-Lys(Dde)-OH, except that the side-chain ivDde group is considerably more stable to piperidine than Dde, and is less prone to migrate from protected to unprotected lysine side-chains ^[1].When removing ivDde in the presence of allyl based protecting groups, allyl alcohol should be included in the deprotection solution to prevent reduction of the allyl group ^[2].
