1. 1-O-Benzyl-2,3-O-iso-propyl-idene-6-O-tosyl-α-l-sorbo-furan-ose
John H Reed, Peter Turner, Atsushi Kato, Todd A Houston, Michela I Simone Acta Crystallogr Sect E Struct Rep Online. 2013 Jun 12;69(Pt 7):o1069-70. doi: 10.1107/S1600536813015638. eCollection 2013.
{(3aS,5S,6R,6aS)-3a-[(benz-yloxy)meth-yl]-6-hy-droxy-2,2-di-methyl-tetra-hydro-furo[2,3-d][1,3]dioxol-5-yl}methyl 4-methyl-benzene-sulfonate), C23H28O8S, the absolute structure and relative stereochemistry of the four chiral centres have been established by X-ray crystallography, with the absolute configuration inferred from the use of l-sorbose as the starting material. The central furan-ose ring adopts a slightly twisted envelope conformation (with the C atom bearing the methyl-benzene-sulfonate substituent as the flap) from which three substituents depart pseudo-axially (-CH2-O-benzyl, -OH and one acetonide O atom) and two substituents pseudo-equatorially (-CH2-O-tosyl and second acetonide O atom). The dioxalane ring is in a flattened envelope conformation with the fused CH C atom as the flap. In the crystal, mol-ecules pack in columns along [010] linked by O-H⋯O hydrogen bonds involving the furan-ose hy-droxy group and furan-ose ether O atom.
2. The methanol and ethanol solvates of 4-glutarato- N, N-diiso-propyl-tryptamine
Marilyn Naeem, Barbara E Bauer, Andrew R Chadeayne, James A Golen, David R Manke Acta Crystallogr E Crystallogr Commun. 2022 Sep 22;78(Pt 10):1034-1038. doi: 10.1107/S2056989022009094. eCollection 2022 Oct 1.
The solid-state structures of two solvated forms of 4-glutarato-N,N-diiso-propyl-tryptamine were determined by single-crystal X-ray diffraction, namely, 5-[(3-{2-[bis(propan-2-yl)azaniumyl]ethyl}-1H-indol-4-yl)oxy]-5-oxopentanoate meth-anol monosolvate, C21H30N2O4·CH3OH, and the analogous ethanol monosolvate, C21H30N2O4·C2H6O. In both compounds, the 4-glutarato-N,N-di-iso--pro-pyl-tryptamine exists as a zwitterion with a protonated tertiary ammonium and a deprotonated glutarato carboxyl-ate. The tryptamine zwitterions and alcohol solvates in both structures combine to produce near identical hydrogen-bonding networks, with N-H⋯O and O-H⋯O hydrogen bonds joining the mol-ecules together in two-dimensional networks parallel to the (100) plane.
