Brønsted Acid‐Catalyzed Tandem Aldol Condensation/1,4‐Aza‐Michael Addition: N 2 ‐Selective Alkylation of Tetrazoles

Herein, we disclose a Brønsted acid‐catalyzed tandem aldol condensation/1,4‐aza‐Michael addition strategy to achieve highly N 2 ‐selective alkylation of tetrazoles (N 2 /N 1 > 25:1), and the N 2 ‐selectivity was unambiguously confirmed by single‐crystal X‐ray diffraction. Control...

Conformationally Restricted GalN3 Donors Enable Zinc(II)-Mediated Stereocontrolled Galactosylation

Abstract We report a Zn(II)-mediated stereocontrolled galactosylation with two conformationally restricted GalN3 donors that enables divergent α- and β-glycosylation. The 4,6-O-TIPDS/3-O-Bz donor selectively affords α-GalN3 glycosides, while the 4,6-O-benzylidene/3-O-TIPS donor p...

Side-Chain Length Modulation in Thieno[3,2- c ]isochromene Small-Molecule Donors for High-Performance Ternary Fullerene Organic Solar Cells

Abstract Side-chain engineering is an effective strategy for precisely tuning the crystallinity and active-layer morphology of high-performance bulk-heterojunction (BHJ) organic solar cells (OSCs). To systematically elucidate the side-chain length–property relationship across a c...
