Suzuki-miyaura cross-coupling in acylation reactions, scope and recent developments.

Since the first report and due to its handiness and wide scope, the Suzuki-Miyaura (SM) cross coupling reaction has become a routine methodology in many laboratories worldwide. With respect to other common transition metal catalyzed cross couplings, the SM reaction has been so far less exploited as a tool to introduce an acyl function into a specific substrate. In this review, the various approaches found in the literature will be considered, starting from the direct SM acylative coupling to the recent developments of cross coupling between boronates and acyl chlorides or anhydrides.

Strigolactone analogs as molecular probes in chasing the (SLs) receptor/s: design and synthesis of fluorescent labeled molecules.

Originally identified as allelochemicals involved in plant-parasite interactions, more recently, Strigolactones (SLs) have been shown to play multiple key roles in the rhizosphere communication between plants and mycorrhizal fungi. Even more recent is the hormonal role ascribed to SLs which broadens the biological impact of these relatively simple molecules. In spite of the crucial and multifaceted biological role of SLs, there are no data on the receptor(s) which bind(s) such active molecules, neither in the producing plants nor in parasitic weeds or AM fungi.

One-pot regio- and stereoselective synthesis of α'-methoxy-γ-pyrones: biological evaluation as mitochondrial respiratory complex inhibitors.

The one-pot construction of functionalized α'-methoxy-γ-pyrones is detailed. Starting from α,α'-dimethoxy-γ-pyrone, molecular diversity is attained by a regio- and stereoselective desymmetrization using allyllithium followed by vinylogous aldol reaction. Mechanistic considerations including density functional theory calculations and insightful experiments have been gathered to shed light on this complex multistep process.
