Efficient syntheses of streptocarpone and (±)-a-dunnione
(2007)
An efficient divergent synthesis of both streptocarpone and racemic α-dunnione from lawsone are described. A one-pot, formal [3+2] cyclization to form a furanonaphthoquinone directly provided a common intermediate.
Grids II: Aromatic Acidity and Basicity
Cuadrículas II: Acidez y Basicidad Aromática
(2021)
The effect of substituents on the acidity of benzoic acids
and basicity of anilines has been organized in grids to
demonstrate the inductive and resonance effects. The
relation between structure and pKa is emphasized ...
Orbitals in general chemistry, Part III: Consequences for Teaching
(2021)
In Part III of this series, we undertake a critique of the nature of application of orbitals to describe or to explain the structure and the
binding within molecules and materials. Teaching orbitals in introductory chemistry ...

We use sudoku puzzles to help the students (i) learn the correspondence between the names of the amino acids, their abbreviations, and codes and (ii) learn the correspondence between the names of the functional groups, ...
Crystal structure of 4-[(adamantan-1-yl)amino]naphthalene-1,2-dione
(2019)
The title compound, C20H21NO2, an example of a stable 1,2-naphthoquinone, was determined by single-crystal X-ray diffraction analysis at 100 K. This structure illustrates steric buttressing of the adamantanyl group, forcing ...
