Descrizione

Descrizione generale

This orthogonally-protected diaminobutyric acid 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] and from side-chain to γ-amino group ^[2].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 ^[3].
