Non-chelation control in allylations of α-oxy ketones using group-14 allylatranes - Nature Communications The syn-selective additions of α-oxy carbonyls via a chelation pathway are well established, but the anti-selective additions via a non-chelation pathway remain unexplored. Here, the authors report th...

Non-chelation control in allylations of α-oxy ketones using group-14 allylatranes has been published online (open-access). We have solved a selectivity challenge that researchers have struggled with for a long time. Great work by Yuya and Kokoro! #Pisky

Precise Synthesis of Pyrene-Based Molecular Nanocarbons Driven by Dehydro-Diels–Alder Reactions Molecular nanocarbons are critical bridges between small polycyclic aromatic hydrocarbons and extended graphene lattices, driving advances across materials science, optoelectronics, and quantum technologies. However, the atomically precise synthesis of such systems, particularly those featuring K-region and cove-type topologies, remains an enduring challenge. Here, we present a de novo modular strategy that overcomes this constraint by directing K-region growth via annulation of preorganized aryl acetylnaphthalene precursors with acetylenedicarboxylate. The strategy mirrors the hierarchical construction of pyrene by formally inserting naphthalene fragments into spatially defined molecular scaffolds. This method integrates Suzuki–Miyaura coupling with a Zn(OTf)2-catalyzed cascade comprising Friedel–Crafts alkylation, dehydro-Diels–Alder cycloaddition, and dehydrogenative aromatization. The platform affords structurally diverse pyrene-based molecular nanocarbons with programmable control over topology and dimensionality, spanning linear, contorted, and three-dimensional π-architectures. These results establish a generalizable blueprint for bottom-up synthesis of complex carbon-rich architectures with atomic precision.

(Chiro)optical Properties of π-Extended Spiro-Double Carbo[7]helicene Helical nanographenes are a fascinating class of π-extended chiral nanocarbons, where structural helicity imparts intrinsic chirality and unique optoelectronic properties to the rigid carbon framework. In this work, we synthesized a hexa-peri-hexabenzocoronene-based π-extended spiro-double carbo[7]helicene. The helical distortion of the structure was unambiguously confirmed by X-ray crystallography. The optical properties were explored through UV–Vis absorption, fluorescence, and phosphorescence measurements, complemented by density functional theory (DFT) calculations. Remarkably, the π-extended spiro-double carbo[7]helicene exhibited thermally activated delayed fluorescence (TADF) at room temperature and phosphorescence at low temperatures. Chiral HPLC successfully resolved the enantiomers into three fractions: (PP), (MM), and the meso forms (PM)/(MP), and chiroptical studies of the pure enantiomers revealed a moderately high glum value of 1.58 × 10–3. Finally, the origin of the observed dissymmetry factors was rationalized by analyzing the transition electric dipole moments (TEDM) and transition magnetic dipole moments (TMDM) derived from time-dependent density functional theory (TD-DFT) calculations.
