Concise, stereoselective syntheses of cis-nemorensic acid and 4-hydroxy-cis-nemorensic acid via tandem carbonyl ylide formation-cycloaddition.
[reaction: see text] 1,3-Dipolar cycloaddition of propargyl bromide with the carbonyl ylide derived from 6-diazoheptane-2,5-dione is the key step in concise syntheses of cis-nemorensic acid and 4-hydroxy-cis-nemorensic acid.
