Notes: The oxidation product obtained by treatment of bulbocapnine methyl ether (2a) with iodine in ethanol/water is not the tetradehydroaporphinium salt 4 as assigned by Gadamer & Kuntze, but a dimer of structure 3. Reduction of 3 with zinc in dilute sulfuric acid gives rac-bulbocapnine methyl ether, whereas reduction with complex hydrides affords the diastereomeric dimers 7a and 7b.
