Selective Opening of Ring C in the Morphine Skeleton by an Unexpected Cleavage of the C5−C6 Bond in Cycloadducts of Thebaine and Acyl Nitroso Compounds
摘要:
[GRAPHICS]Acyl nitroso cycloadducts of the alkaloid thebaine undergo an unexpected cleavage of the C5-C6 bond when treated with 2 equiv of samarium(II) iodide in THF to give novel hexahydrobenzazocine products. A proposed mechanism for the transformation involves rearrangement of the initial radical anion.

Periodate oxidation of hydroxamicacids in the presence of conjugated dienes gives, in good yield, N-acyl-3,6-dihydro-2H-1,2-oxazines derived, presumably, from nitrosocarbonylintermediates.
在共轭二烯存在下高肟酸的异羟肟酸的高产率得到N-酰基-3,6-二氢-2 H -1,2-恶嗪,大概是由亚硝基羰基中间体衍生而来的。
