New reagent for the introduction of Boc protecting group to amines: Boc-OASUD

A new reagent, tert-butyl (2,4-dioxo-3-azaspiro [5,5] undecan-3-yl) carbonate (Boc-OASUD) for the preparation of N-Boc-amino acids is described. The Boc-OASUD reacts with amino acids and their esters at room temperature in the presence of a base and gives N-Boc-amino acids and their esters in good yields and purity. Introduction of the Boc group takes place without racemization. The Boc-OASUD, being a solid and more stable, is a better alternative to di-tert-butyl dicarbonate which is low melting and has to be dispensed in plastic containers than glass because of its poor stability.

Studies of Neurokinin Antagonists. 4. Synthesis and Structure-Activity Relationships of Novel Dipeptide Substance P Antagonists: N2--L-prolyl>-N-methyl-N-(phenylmethyl)-3-(2-naphthyl)-L-alaninamide and Its Related Compounds

As an extension of our studies on discovering a novel substance P (SP) antagonist, we modified the previously reported dipeptide, N2-2-(1H-indol-3-ylcarbonyl)-L-lysyl>-N-methyl-N-(phenylmethyl)-L-phenylalaninamide (2b).The lysine part in 2b was first optimized to a (2S,4R)-hydroxyproline derivative (3h), which is 2-fold more potent than 2b in SP binding assay using guinea pig lung membranes.Next we modified the 1H-indol-3-ylcarbonyl part in 3h.Introduction of a methyl group at the indole nitrogen enhanced the oral activity, while retaining the binding activity.Finally, we modified the phenylalanine part to culminate in the most potent compound 7k (FK888), which is a potent SP antagonist with NK1 selectivity as well as oral activity.
