Catechol dichloromethylene ether

A carboxylic acid group may be introduced into the 2-position of dibenzofuran by Friedel-Crafts reaction with 2,2-dichloro-l,3-benzodioxole (catechol dichloromethylene ether) and hydrolysis of the resultant ester. Similarly, reaction with methylphenylcarbamoyl chloride produces the 2-(N-methyl-yV-phenylcarboxamide) or the 2,8-disubstituted derivative under more stringent conditions. Controlled reduction of these amides with lithium aluminum hydride supplies the corresponding aldehydes. ... [Pg.66]

The reaction of organoboranes with catechol dichloromethylene ether in the presence of methyllithium provides a synthesis of symmetrical ketones (Eq. 34) From the result of a crossover experiment by using a mixture of two different trialkylboranes, the reaction was confirmed to proceed through intramolecular reaction pathways. [Pg.79]
