first world. One of the most extended methods for its identification is based on the detection of a characteristic red pigment in the patient samples, named [12]-granadaene (1). In this article, we present a modular and flexible approach to simple analogues of this ornithine rhamno-polyene 1 and the elucidation of the most important features of its structure: the absolute configuration at C-27, the

(MCRs) is highly sought-after in chemical synthesis. However, catalytic asymmetric MCRs, particularly involving radical species, remain largely underdeveloped due to the exceptionally high reactivity of open-shell radical species. Herein, we report a metallaphotoredox-catalyzed asymmetric three-component method to access a diverse array of enantio-enriched α-alkenyl phosphonates from readily available

Judicious substrate design allows interruption of the classical Bischler–Napieralskireaction, providing access to a range of diversely substituted tetracyclic spiroindolines. These complex polycyclic scaffolds are valuable building blocks for the construction of indole alkaloids, as showcased in a concise total synthesis of (±)-akuammicine.
