Although syntheses of this class of compounds have been extensively explored, all known approaches are based on annulations, relying on the union of properly pre-functionalized building blocks. To complement these studies, here we showcase an alternative, non-annulative entry to anthracyclines, starting from a polynuclear arene. Specifically, tetracene was converted to idarubicinone, an aglycone of the FDA approved anthracycline idarubicin, by a judicious orchestration of Co- and Ru-catalyzed arene oxidation and a novel dearomative hydroboration. This global functionalization strategy, a combination of site-selective arene- and dearomative-functionalizations, provided the key anthracycline framework in five operations and enabled rapid and controlled access to idarubicinone. Another class of compound deriving from polyketide synthases are the cannabinoids. Having a long history of use, yet controversial nature Cannabis offers the possibility for the treatment of many diseases. Reports are varied, however, possibly due to the affect of numerous and under-studied minor cannabinoids. A small library of minor cannabinoids were prepared and tested for their anti-inflammatory pain with the goal of discovering a novel lead compound. Specifically, cannabimovone was prepared in biomimetic fashion and displayed a remarkable ability to stimulate the production of cytokines in a BV-2 mouse microglial cell line under inflammatory response.","abstract_html":"Anthracyclines are archetypal representatives of tetracyclic type II polyketide natural products that are widely used in cancer chemotherapy.
