Аннотация:
Treatment of 6β-chloro-6-deoxycodeine 1 with Pd(PPh3)4 yields 6-demethoxythebaine 2 and the π-allylic palladium complex 3, which further reacts with RZnX to give the cross-coupling product of the allylic ligand and R (compounds 5 and 6, respectively). The same products are formed upon reaction of 6β-chloro-6-deoxycodeine 1 with RZnX in the presence of catalytic amounts of Pd(PPh3)4.
