Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, EarlyView.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

2-(4-Chlorophenyl)acetamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2011
In the title compound, C(8)H(8)ClNO, the acetamide group is twisted out the benzene plane with a dihedral angle of 83.08 (1)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming layers parallel to the ab plane.

N-(3-Chlorophenyl)acetamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2008
The conformation of the N-H bond in the structure of the title compound (3CPA), C(8)H(8)ClNO, is anti to the meta-chloro substituent, in contrast to the syn conformation observed for the ortho-chloro substituent in N-(2-chloro-phen-yl)acetamide, syn to both the ortho and meta chloro substituents in N-(2,3-dichloro-phen-yl)acetamide, and syn to the ...

O‑Glycosylation Enabled by N-(Glycosyloxy)acetamides

, 2018
A novel glycosylation protocol has been established by using N-(glycosyloxy)­acetamides as glycosyl donors. The N-oxyacetamide leaving group in donors could be rapidly activated in the presence of Cu­(OTf)2 or SnCl4 under microwave irradiation.

N-(2,3-Dimethylphenyl)acetamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
The conformation of the N-H bond in the structure of the title compound, C(10)H(13)NO, is syn to both the 2- and 3-methyl substituents on the aromatic ring, and is anti to the C=O bond. N-H⋯O hydrogen bonds link the mol-ecules into supra-molecular chains.
