Gayraud, Oscar; Laroche, Benjamin; Casaretto, Nicolas; Nay, Bastien published their research in Organic Letters in 2021. The article was titled 《Synthesis of a Biomimetic Tetracyclic Precursor of Aspochalasins and Formal Synthesis of Trichoderone A》.SDS of cas: 78782-17-9 The article contains the following contents:
Aspochalasins are leucine-derived cytochalasins. Their complexity is associated with a high degree of biosynthetic oxidation, herein inspiring a two-phase strategy in total synthesis. We thus describe the synthesis of a putative biomimetic tetracyclic intermediate. The constructive steps are an intramol. Diels-Alder reaction to install the isoindolone core of cytochalasins, whose branched precursor was obtained from a stereoselective Ireland-Claisen rearrangement performed from a highly unsaturated substrate. This also constitutes a formal synthesis of trichoderone A. In the experiment, the researchers used Bis[(pinacolato)boryl]methane(cas: 78782-17-9SDS of cas: 78782-17-9)
Bis[(pinacolato)boryl]methane(cas: 78782-17-9) belongs to organoboron compounds.SDS of cas: 78782-17-9 Organoboron compounds are versatile intermediates and as such are some of the most important classes of reagents in modern organic chemistry. This stems from their ease of preparation combined with their ability to undergo a broad range of chemical transformations.
