Two papers published with participation of Jonas Wunsch and Daniel Eppel.
The article, co-authored by Jonas Wunsch and A. Stephen K. Hashmi, entitled "Gold-catalyzed synthesis of phosphonate-substituted oxetan-3-ones — an easy access to highly strained HWE reagents" was published in the journal Organic Chemistry Frontiers. The team has developed a method for the synthesis of phosphonate-substituted oxetan-3-ones. These can be used as HWE reagents, upon reaction with aldehydes to get otherwise difficult to obtain alkenes. Due to the easy accessibility of these highly strained HWE reagents and the possibility to further transfer these substrates, this methodology might become attractive as new tool for natural product synthesis.
Another article co-authored by Daniel Eppel and A. Stephen K. Hashmi entitled "Gold(III) Meets Azulene: A Class of [(tBuC∧N∧C)AuIII(azulenyl)] Pincer Complexes " was published in Organometallics. In the past decade high interest in the development of efficient and modular azulene syntheses has arisen, which can be rationalized by its extraordinary properties and the potential for material science, bioimaging, medicinal chemistry, and stimuli-response materials. The team has developed a synthetic route to new gold(III) complexes.
From a [(tBuC∧N∧C)AuCl] complex as a precursor, a substitution by different azulene moieties was achieved. Because of the extraordinary photophysical properties of both substituted [(C∧N∧C)Au] compounds and azulene building blocks, the fusion of these generated organometallic azulene/gold(III) pincer hybrids was possible. The complexes show HOMO/LUMO gaps, which made them candidates for perovskite solar cells.
Congratulations to the working group of Hector Fellow A. Stephen K. Hashmi!
