Total Synthesis of the Spirocyclic Bis‐Indole Alkaloid (−)‐Owerreine via a [4+2] Annulation

Angewandte Chemie, EarlyView.
The total synthesis of the bis‐indole alkaloid (−)‐owerreine has been accomplished by a diastereoselective [4+2] annulation between an enamine and an α,β−unsaturated indolenine precursor to form the 3‐spirocyclic tetrahydropyridine linkage of the natural product. DFT calculations allow an understanding of the mechanism of the key annulation.

Photoinduced Generation of (Boryl)Silyl and (Chloro)Silyl Radicals: Access to Trisubstituted Silylboranes and Chlorosilanes

Angewandte Chemie, EarlyView.
A versatile photoinduced hydro(boryl)silylation and hydro(chloro)silylation of alkenes to construct trisubstituted silylboranes and chlorosilanes was achieved through in situ generation of (boryl)silyl radicals or (chloro)silyl radicals. This mild methodology affords high chemoselectivity and broad functional group tolerance to enable direct access to ...

Photocatalytic Cross‐Coupling of Phenols and Heteroaryl Halides With Machine Learning‐Guided Reaction Prediction

Angewandte Chemie, EarlyView.
Photocatalytic cross‐coupling: A redox‐neutral photochemical method enables direct C(sp2)─C(sp2) bond formation between phenols and heteroaryl halides using an organic dye and base. Complementary radical generation allows efficient cross‐coupling in up to 91% yield. Mechanistic studies, DFT, HTE, and machine learning rationalize and predict reactivity,

Sequential Homo‐ and Hetero‐Coupling of Isocyanide and Carbon Monoxide Mediated by Acyclic Imino(silyl)Silylene

Angewandte Chemie, EarlyView.
We demonstrate the sequential reactions between an imino(hypersilyl)silylene and aryl isocyanide or carbon monoxide as a molecular‐level model of the Fischer–Tropsch process, providing systematic and detailed insight into C–C bond formation during the homologation of C1 building blocks.
