Family of β-Propeller Diels–Alderases Directs cis -Decalin Formation in Polyketide Biosynthesis

Er Juan Zhao, Qing Yan Ling, Xiu Xiu, Shuang He Liu et autres

Abstract Decalin-forming Diels–Alderases (pericyclases) exemplify how Nature repeatedly recruits unrelated protein folds to control [4 + 2] cycloadditions, yet exo-selective intramolecular Diels–Alder (IMDA) reactions that yield cis-fused decalins remain rare and poorly understood. Here, we uncover a previously unrecognized bacterial pericyclase family …

Rhodopyran, a carboxylated hexahydrocyclopenta[ b ]pyran from Rhodococcus

Enjuro Harunari, Sara Fushimi, Yasuhiro Igarashi

A new bicyclic metabolite, rhodopyran ( 1 ), was isolated from the culture broth of Rhodococcus sp. strain RD066637. The planar structure was elucidated by 1D/2D NMR analyses and HRMS spectrometry, and the relative configuration was assigned from vicinal coupling constants and …

Synthesis of farinomaleins and their antimicrobial activities

Md. Masud Rana, Taku Oshima, Emi Horiuchi, Yasuhiro Igarashi et autres

A single-step synthesis of farinomalein A, a naturally occurring maleimide, by the radical-mediated introduction of an isopropyl group to bromomaleic anhydride and one-pot maleimide formation with β-alanine is reported. Antimicrobial testing of natural and unnatural farinomaleins synthesized using this protocol demonstrates that …
