A convenient totalsynthesis of chromomoric acid B methylester 1 and the first synthesis of chromomoric acid Fmethylester 2 have been described. A one-pot Michael addition-enolate trapping sequence afforded ketone 5 which after a few steps was converted to 1. Retro Diels-Alder reaction of ester 7 afforded enone 9 which was then transformed to the target molecule 2 through hydrogenation and α-hydroxylation
