An expedient synthesis of a new family configurationally stable dioxa[6]helicenes was established using sequential helicoselective organocatalyzed heteroannulation/eliminative aromatization via enantioenriched fused 2-nitro dihydrofurans featuring both central and helical chiralities. Starting from simple achiral precursors, broad range these previously unknown chiral heterocyclic scaffolds were obtained with good efficiency, their proceeded very high enantiopurity retention in most cases.

Enantioselective construction of small molecules displaying a configurationally stable helical shape built on fused-tetracyclic core is daunting synthetic challenge even more pronounced when five-membered rings are incorporated in the structure. The resulting higher configurational lability strongly hampers their access, and therefore development new efficient methodologies timely highly desirable. In this context, we describe padlocking approach

Abstract Porphyrin cage-compounds are used as biomimetic models and substrate-selective catalysts in supramolecular chemistry. In this work we present the resolution of planar-chiral porphyrin cages determination their absolute configuration by vibrational circular dichroism combination with density functional theory calculations. The chiral porphyrin-cages form complexes achiral viologen-guests upon binding one axial enantiomorphs guest is bound selectively, indicated...

A single-crystal-to-single-crystal solid-state reaction of vinylogous donor–acceptor cyclopropanes is documented. The enantiospecific synthesis new products, distinct from those obtained in solution, achieved for the target compounds. Photopolymerization occurred upon X-ray exposure to crystals. Notably, one case, this reactivity exhibits selectivity since an ordered arrangement polymers and unreacted cocrystallized monomeric conformers has been observed. Structural characterization complete...

Abstract An access to functionalised eight‐membered carbocyclic ring compounds was developed by simply stirring an unusual vinylogous Donor‐Acceptor Cyclopropane (DAC) in boiling o ‐xylene. Both experimental and computational studies were performed explain the diastereoselectivity/regioselectivity transfer observed provide overall picture of mechanism. magnified image

Sponges are prolific producers of specialized metabolites with unique structural scaffolds. Their chemical diversity has always inspired natural product chemists working in drug discovery. As part their metabolic filter-feeding activities, sponges known to release molecules, possibly including metabolites. These released "Exo-Metabolites" (EMs) may be considered as new reservoirs that could collected from the water column while preserving marine biodiversity. The present work aims determine...
