Concise Syntheses of Insect Pheromones Using Z-Selective Cross Metathesis [PDF]

open access: yes, 2013
The use of insect sex pheromones to limit specifically targeted pest populations has gained increasing popularity as a viable, safe, and environmentally friendly alternative to insecticides. While broad-spectrum insecticides are toxic compounds that have

Bio‐Based Polyurethanes: Mechanical Performance, Structure–Property Relationships, and Future Directions

open access: yesJournal of Polymer Science, Volume 64, Issue 9, Page 1860-1894, 1 May 2026.
This review examines bio‐based polyurethanes from renewable feedstocks, focusing on structure‐property relationships governing mechanical performance. It analyzes reinforcement strategies, benchmarks against petrochemical counterparts, and explores future directions, including non‐isocyanate routes and circular economy integration for sustainable high ...

Ruthenium-catalysed Z-selective cross metathesis of allylic-substituted olefins [PDF]

open access: yes, 2013
The Z-selective cross metathesis of allylic-substituted olefins is explored with recently developed ruthenium-based metathesis catalysts. The reaction proceeds with excellent stereoselectivity for the Z-isomer (typically >95%) and yields of up to 88% for

Synthesis of a Carbon‐Linked Acyldepsipeptide Derivative

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 15, 22 April 2026.
The synthesis of a methylene‐linked acyldepsipeptide (ADEP) is reported. Success relied upon an improve method to generate a versatile vinyl glycine methyl ester synthon and a rationally optimized Grubb’s metathesis. NMR and in silico studies revealed an unusual trans–trans proline orientation for this new unnatural ADEP analog, advancing the ...
