Описание
A simple aporphine alkaloid found in Stephania sasakii Hayata, the alkaloid has
[α]D - 90.6° (MeOH) and forms pale yellow needles when crystallized from
Me2CO-Et20. The alkaloid occurs in the non-phenolic fraction of the alkaloidal
extract from the plant and with AC20 in pyridine forms the O-acetate. The
structure of the base has been determined by spectroscopic methods. The
absolute configuration of the 6 -position has been established as R from the
ORD determinations but as yet the steric configuration of the hydroxyl group
remains to be clarified.
