Abstract:
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 .
