General description

This orthogonally-protected ornithine derivative is based on the hindered Dde variant ivDde. The side-chain ivDde group is considerably more stable to piperidine than Dde and is less prone to migrate from protected to unprotected 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].

See references [3, 4] for applications.

The product number for this product was previously 04-12-1203.
