Lewis acid catalyzed reaction of 2-furaldehyde and secondary amines results in the formation of 4,5-diaminocyclopent-2-enones exclusively as the trans diastereomers: computational studies support the stereochemistry of the adducts as arising from a thermal conrotatory pi4a electrocyclization of an initial ring-opened intermediate (a deprotonated Stenhouse salt).

We present a one-photon visible light-responsive micellar system for efficient, on-demand delivery of small molecules. Release is mediated by a novel class of photochromic material - donor-acceptor Stenhouse adducts (DASAs). We demonstrate controlled delivery of small molecules such as the chemotherapeutic agent (paclitaxel) to human breast cancer cells triggered by micellar switching with low ...

We report photochromic donor-acceptor Stenhouse adducts (DASAs) capable of fully reversible photoisomerization with visible light in organic solvents including chloroform, acetonitrile and benzene. The rates of photoisomerization and thermal reversion can be tuned by altering the electronics of the donor adduct. X-Ray crystallography and photo-NMR experiments unambiguously establish molecular s...

In 1981, Lawrence Stenhouse argued that too much research had been conducted for the world and not enough village. 2021, as we mark 40-year anniversary of Stenhouse’s provocation, th...

David Stenhouse’s classical definition of intelligence as “adaptively variable behavior within the lifetime of the individual” (Stenhouse, 1974, in Trewavas, 2003), widely accepted among biologists, explicitly refers to behavior, requiring thus a previous understanding of this concept. Here, we are providing a biologists’ perspective, which may differ from that of psychologists, economists or c...

The effects of solution-state dielectric and intermolecular interactions on the degree charge separation provide a route to understanding switching properties concentration dependence donor–acceptor Stenhouse adducts (DASAs). Through solvatochromic analysis open-form DASA in conjunction with X-ray diffraction computational theory, we have analyzed ionic character series DASAs. First- third-gene...
