Gram Scale Synthesis of (±)-Gregatin A via 1, 3-dipolar Cycloaddition Strategy
Here, we present a 6-step gram-scale synthesis of (±)-gregatin A, a fungal polyketide characterized by an alkylated furanone core origi-nally isolated from Cephalosporium gregatum. The synthetic route features an intermolecular 1,3-dipolar cycloaddition, a Mo-mediated disconnection of isoxazole skeleton, and an acid-mediated desilylation/enamine ...Yiming Ding +7 more

This paper announces the results of certain 1, 3-dipolar cycloadditions to polycyclic aromatic hydrocarbons (PAHs). The 1, 3-dipoles generated from cyclobutene diester epoxides thermally reacted with PAHs to give cycloadducts. This reaction demonstrated the remarkable ability of these 1, 3-dipoles to disrupt an aromatic system by adding across specific
