Isopropyl 2,3,4,6-tetra-O-acetyl-β-D-glucopyran­oside

The title compound, C₁₇H₂₆O₁₀, was formed by a Koenigs–Knorr reaction of 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide and propan-2-ol. The central ring adopts a chair conformation. The crystal does not contain any significant inter­molecular inter­actions.

n-Propyl 2,3,4,6-tetra-O-acetyl-β-D-glucopyran­oside

The title compound [systematic name: (2R,3R,4S,5R,6R)-2-(acet­oxy­meth­yl)-6-propoxytetra­hydro-2H-pyran-3,4,5-triyl triacetate], C₁₇H₂₆O₁₀, was formed by a Koenigs–Knorr reaction of 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide and n-propanol. The central ring adopts a chair conformation. The crystal does not contain any significant inter­actions such as hydrogen bonds.

N-(β-Carb­oxy­eth­yl)-α-isoleucine

The title compound, {2-[(2-carbamoyleth­yl)amino]-3-methyl­penta­noic acid}, C₉H₁₈N₂O₃, is of inter­est with respect to its biological activity. It was formed during an addition reaction between acryl­amide and the amino acid isoleucine. The crystal structure is a three-dimensional network built up by inter­molecular N—H...O and O—H...N hydrogen bonds.
