Absolute configuration of indoline alkaloids from Geissospermum reticulatum

The absolute configuration (AC) of (+)-2R,7R,15R,17S,19S-10-demethoxy-12-hydroxy-17,19-epoxygeissovelline (1), a main aspidospermatan-type indoline alkaloid from Geissospermum reticulatum, was established by vibrational circular dichroism (VCD), facilitating deduction of the AC of all structurally r...

Description
Summary:The absolute configuration (AC) of (+)-2R,7R,15R,17S,19S-10-demethoxy-12-hydroxy-17,19-epoxygeissovelline (1), a main aspidospermatan-type indoline alkaloid from Geissospermum reticulatum, was established by vibrational circular dichroism (VCD), facilitating deduction of the AC of all structurally related alkaloids isolated from this plant.
