An enantioselective formal synthesis of (−)-englerin A (1) is reported. Key to the strategy is a Rh-catalyzed [4+3] cycloaddition reaction between furan 10 and diazoester 11 that, following an intramolecular aldol condensation, produces the tri-cyclic scaffold of englerin. This strategy also provides a rapid, efficient and stereoselective access to the biologically significant core motif of the guaiane sesquiterpenes.
