Abstract:O,O‐Dimethylipecoside is orthorhombic, space group C2221, with a = 29.57 (3), b = 825 (1), c = 29.52 (3) Å, Z = 8. The structure was solved by tangent formula refinement of diffractometer data collected with Cu radiation. Full‐matrix least‐squares refinement resulted in a final R of 0.141 for 2159 reflexions. The dihydroisoquinoline ring has the expected geometry. The dihydropyranyl ring is a ‘half‐chair’ and the glucose ring is in the chair form. The absolute configuration was assigned from the knowledge that… 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.
