Areno [E]indols, preparation method and application as intermediates in the synthesis of products with antitumoral activity

The areno[e]indols have the formula (I). The methods comprises: (a) reacting (VI) with an aldehyde Ar"--CHO to obtain (VII); (b) oxidizing (VII) to yield the cetone (VIII); (c) reating (VIII) with a strong base and thereafter with an acycle chloride ClCOR

SYNTHESIS OF FIVE-MEMBERED HETEROARYLMETHYL p-TOLYLSULFONES FROM HETEROARENEMETHANOLS UNDER ACIDIC CONDITIONS: SCOPE AND LIMITATIONS

It is shown that the successful conversion of five-membered heteroarenemethanols into the corresponding heteroarylmethyl p-tolylsulfones by treatment with sodium p-toluenesulfinate under acidic conditions depends on the stability of the intermediate heteroarylmethyl carbocations.
