Deciphering the hydrogen-bonding scheme in the crystal structure of triphenylmethanol: a tribute to George Ferguson and co-workers
Autor: Rosa L. Meza-León, Aldo Guillermo Amaro Hernández, Sylvain Bernès, Tomasa Rodríguez Tzompantzi
Publikováno v: Acta Crystallographica. Section C, Structural Chemistry
The disordered crystal structure of tri­phenyl­methanol features tetra­hedral chiral clusters formed through weak hydrogen bonds, leading to the formation of three-dimensional supra­molecular motifs having left or right handedness.
The cryst

Publikováno v: The Journal of Organic Chemistry. 84:2126-2132
The stereocontrolled synthesis of naturally occurring products containing a 5,5-spiroketal molecular structure represents a major synthetic problem. Moreover, in a previous work, the stereocontroll...
