Photochemisch erzeugte Oxetane als Schlüssel zur endergonen Cyclopropansynthese

Angewandte Chemie, EarlyView.
Eine neuartige Oxetan‐zu‐Cyclopropan‐Umlagerung eröffnet einen atomökonomischen Zugang zu dicht funktionalisierten Cyclopropanen aus Furanen und photochemisch aktivierten Aldehyden. Die erhaltenen Strukturen erschließen komplexe bioaktive Motive und fungieren als vielseitige Plattform für die asymmetrische Cyclopropansynthese.

Photogenerated Oxetanes as a Gateway to Uphill Cyclopropanation

Angewandte Chemie International Edition, EarlyView.
An atom‐economical route to densely functionalized cyclopropanes from furans and photochemically activated aldehydes is enabled by a unique oxetane‐to‐cyclopropane rearrangement. These cyclopropanes can be used to access complex bioactive scaffolds and serve as a platform for asymmetric cyclopropane synthesis.

Priming bumble bees with caffeine, odour of the target crop, and a food reward, has minimal effects on fruit crop pollination and yield in a semi-commercial setup

Journal of Pollination Ecology
Caffeine is a widely occurring plant defence chemical that occurs in the nectar of some plants, e.g. Coffea or Citrus spp., where it may influence pollinator behaviour to enhance pollination.

Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

Applications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.
