Synthesis of tetrahydrodicranenone B
Abstract
The naturally occurring cyclopentenone, tetrahydrodicranenone B (1), has been synthesised from 6-methoxyindanone by a route which involves reductive alkylation and ozonolysis to the key cyclopentenone (3), followed by elongation of the lower side chain to give the alcohol (7), and functional group manipulation.
