Natural products have long been important inspirations for the development of chemical methodologies, theories, and technologies, and ultimately, discoveries of new drugs and materials. Chemical syntheses have traditionally yielded individual or small groups of natural products; however, methodology development allowing the synthesis of a large collection of natural products remains scarce. Here, we
Both, natural and non-natural antipodes of yohimbine (1) and β-yohimbine (2) have been synthesized from the tetracyclic keto ester 12 using second order asymmetric transformation in its resolution step.
