The title compound, C14H21BrO3, comprises a seven- (C7) and three six-membered (1 × O2C4 and 2 × C6) rings, and each adopts a conformation based on a chair. Stability to the molecular structure is afforded by an intramolecular O—H
Br hydrogen bond. In the crystal structure, molecules are arranged into a helical supramolecular chain along the b axis, linked by C—HO interactions, where the O-atom acceptor is one of the dioxane O atoms. The crystal studied was found to be a racemic twin. The major component was present 94% of the time.

The cyclohexyl ring in the title compound, C12H15ClO2Se, has a chair conformation with the 4-hydroxy group occupying an axial position; the other non-H substituents occupy equatorial positions. Molecules aggregate via O—HO hydrogen bonds into a supramolecular helical chain.

In the title compound, C13H22O4, the acetonide ring adopts an envelope conformation with one of the O atoms as the flap atom, whereas a twisted conformation is found for the furanose ring. Centrosymmetric eight-membered {OCOH}2 synthons involving the hydroxy H and acetonide O atoms are found in the crystal structure. These are linked into a supramolecular chain in the a-axis direction via C—HO contacts.

The title compound (systematic name: 3,4-dihydroxy-3-phenylfuran-2-one), C10H10O4, features a five-membered γ-lactone ring with an envelope conformation at the C atom carrying the hydroxy group without the phenyl substituent. In the crystal, supramolecular chains mediated by O—HO hydrogen bonding are formed along the a-axis direction. These are consolidated in the crystal structure by C—HO contacts.

The title compound, C13H16O, comprises two fused five-membered rings. Each ring has an envelope conformation, with the ether O atom in the furanose ring, and the CMe2 atom in the acetonide ring as the flap atoms. In the crystal, centrosymmetrically related molecules associate via hydroxy–ether O—HO hydrogen bonds and the resulting dimers are linked into a supramolecular chain with a flattened topology via C—HOhydroxy contacts, and aligned in the a-axis direction.

The experimental models of dicotyledonous cytoplasmic and plastid-located glutamine synthetases unveil a conserved eukaryotic-type decameric architecture, with subtle structural differences in M. truncatula isoenzymes that account for their distinct herbicide resistance.
