Reduction of 2-phenylindole
gave the dihydro derivative which was hydrogenolysed to give bibenzyl-2-amine.
The latter was best converted into 9,10-dihydrophenanthrene by decomposition of
the derived azosulphone. Several methoxydihydrophenanthrenes, including
orchinol methyl ether, were prepared by this route. ��� Conversion of dihydrophenanthrenes into
phenanthrenes may be conveniently effected by benzylic bromination followed by
dehydrobromination.
还原 2-苯基吲哚
得到二氢衍生物,氢解后得到 2-氨基联苄。
通过分解衍生出的偶氮砜,后者被最好地转化为 9,10-二氢菲。
后者通过分解衍生出的偶氮砜可转化为 9,10-二氢菲。几种甲氧基二氢菲,包括
通过这种方法制备出了几种甲氧基二氢菲,其中包括兽皮酚甲醚。将二氢菲转化为菲。
将二氢菲转化为菲,可以通过苄基溴化,然后脱氢溴化来实现。
