nucleophilicity in the allylic alkylation with Morita‐Baylis‐Hillman carbonates can be accomplished through the endocyclic double bond in 3‐cyano‐4‐methylcoumarins. The developed reaction provides a straightforward access to functionalized coumarin derivatives of biological and synthetic relevance. Target, highly functionalized products have been chemoselectively and efficiently obtained in very high yield

日期:——
first iridium-catalyzed enantioselective vinylogous allylicalkylation of coumarins is presented. Using easily accessible linear allylic carbonates as the allylic electrophile, this reaction installs unfunctionalized allyl groups at the γ-position of 4-methylcoumarins in an exclusively branched-selective manner generally in high yields with an excellent level of enantioselectivity (up to 99 : 1 er).
The invention provides coumarin compounds, in particular glycosidic coumarin compounds, useful in the treatment of dermatophyte fungal infections.
