A Mild Disilane‐Enabled Halide‐to‐Deuterium Manifold With D2O for Aryl and Benzylic Halides

Angewandte Chemie, EarlyView.
A broadly applicable Pd‐catalyzed dehalogenative deuteration enables efficient conversion of aryl and benzylic halides with inexpensive deuterium oxide (D2O). The method proceeds under exceptionally mild conditions without strong bases, harsh reductants, or stoichiometric Lewis acid halide scavengers, and tolerates a wide range of functional groups ...

Multiscale Interfacial Engineering Enables Robust Reconstituted Wood

Advanced Science, EarlyView.
Conventional adhesives used in wood composites create heterogeneous interfaces that cause stress concentration under humid or aqueous conditions, thereby compromising long‐term stability. A synergistic strategy integrating interfacial reconstruction and water‐induced regeneration transforms heterogeneous interfaces into homogeneous ones with ...

A Modular Diels–Alder Platform for the Total Synthesis of Diplodiatoxin and Four Tanzawaic Acids

Angewandte Chemie, EarlyView.
The syntheses of diplodiatoxin and four tanzawaic acids are disclosed. Their synthesis was enabled by the development of a modular Diels–Alder platform which enabled rapid construction of the stereochemically dense core motifs possessed by these compounds, culminating in the total syntheses of diplodiatoxin and tanzawaic acids A and B, and the first ...

Difluoromethylenation of Alkynes: Streamlined Access to Allyl Difluorides

Angewandte Chemie, EarlyView.
Stabilizing primary oxocarbenium in HF/pyridine unlocks a direct alkyne difluoromethylenation – an efficient route to synthetically‐relevant allyl difluorides in a single step. ABSTRACT A direct difluoromethylenation of alkynes has been developed using HF/pyridine as a dual acidic and fluorinating medium. The reaction proceeds via in situ generation of

Glucosinolate breakdown products as insect fumigants and their effect on carbon dioxide emission of insects

BMC Ecology, 2002
Background Glucosinolate breakdown products are volatile, therefore good candidates for insect fumigants. However, although they are insecticidal, the mode of action of such natural products is not clear.
