Two new methods for the introduction of a 3,3-dimethylallyl group ortho- to a phenolic hydroxy-group and their application to the synthesis of dihydro-6-deoxyjacareubin
Abstract
Two unambiguous methods have been developed for the introduction of the 3,3-dimethylallyl group ortho- to a phenolic hydroxy-group and both methods have been used to prepare dihydro-6-deoxyjacareubin.
