The total synthesis of decarboxyaltenusin (5'-methoxy-6-methyl-[1,1'-biphenyl]-3,3',4-triol), a toxin produced by various mold fungi, has been achieved in seven steps in a yield of 31% starting from 4-methylcatechol and 1-bromo-3,5-dimethoxybenzene, where
Total Synthesis of Citreochlorol Monochloro Analogues via a Catalytically Enantioselective Carbonyl Allylation
Hsieh, Bing-Han,Lin, Cheng-Kun,Wu, Chun-Fu
, (2021/11/22)
An efficient synthetic route to citreochlorol analogues, halogenated polyketide secondary metabolites, is described. The key features are Krische s enantioselective carbonyl allylation, IBr-promoted cyclization, and regioselective epoxide opening. The importance of the route lies in accessing a versatile epoxy ether that enables the formation of citreochlorol monochloro derivatives.
Synthesis of Benzyl Amines via Copper-Catalyzed Enantioselective Aza-Friedel-Crafts Addition of Phenols to N -Sulfonyl Aldimines

A new copper-catalyzed enantioselective aza-Freidel-Crafts reaction between phenols and N-sulfonyl aldimines that provides chiral secondary benzylamines in good to excellent yields and excellent enantioselectivities (up to 99% ee) is disclosed. In particular, excellent scope with alkylimines was observed for the first time. The synthetic utility of the products was demonstrated in the first enantioselective synthesis of a dual orexin receptor antagonist, a compound that contains an amine-bearing stereocenter adjacent to a bis-ortho-functionalized arene.
