Rearrangement and novel enol-ether addition in homoproaporphines
Abstract
The dienone–phenol rearrangements of the two stereoisomers (IIa) and (IIb) of 2,3,7,8,9,9a-hexahydro-6-hydroxy-5-methoxy-1-methyl-1H-benzo[de]quinoline-7-spiro-3′-methoxycyclohexa-2′,5′-dien-4′-one and the dienol–benzene rearrangement of the corresponding dienol (VIII) are described. The configurations of (IIa) and (IIb) have been assigned by chemical and spectroscopic methods.
