The crystal structure of coclaurine hydrobromide monohydrate and the absolute configuration of coclaurine.
Abstract The structure and absolute configuration of coclaurine has been determined by X-ray analysis of its hydrobromide monohydrate. The (+)-enantiomer has the D-configuration. The chirality of the molecular structure is correlated with circular dichroism measurements.
Optical rotatory dispersion and absolute configuration—III
Abstract Optical rotatory dispersion measurements on pyrrolidine, piperidine, and tetrahydro-isoquinoline alkaloids indicate that the absolute configuration of the α-asymmetric center may be assigned directly from the dispersion curve, provided either that the nitrogen atom is not protonated, or that the compound contains a chromophore absorbing above 200 mμ.
