The first synthesis of a series of totally orthogonal protected racemic R-(trifluoromethyl)- and R-(difluoromethyl)arginines is described. The key steps of the synthesis are the mild guanidinylation procedure and the selective hydrogenation of a CC triple bond in the presence of a Cbz-group.

Abstract
The first synthesis of a series of totally orthogonal protected racemic R-(trifluoromethyl)- and R-(difluoromethyl)arginines is described. The key steps of the synthesis are the mild guanidinylation procedure and the selective hydrogenation of a CC triple bond in the presence of a Cbz-group.File in questo prodotto:
