Abstract:Analysis of the 'H NMR spectra of 1,4:3,6-bis (thioanhydro)-D-iditol derivatives (la to lc) led to the prediction of the dominant conformations. The configuration and conformation of the symmetric (3) and asymmetric (4) disulphoxides as well as that of the disulphone (5), obtained by oxidation of the 2,5-di-0acetyl-l,4:3,6-bis(thioanhydro)-~-iditol (lb) was also determined. Zusarnmenfassung-Die dominierende Konformation einiger 1,4:3,6-bis(Thioanhydro)-~-idit Derivate (la bis lc) wurde durch 'H NMR Untersuchun… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
