A stereoselective convergent total synthesis of two acetylenic acids, gallicynoic acid G (1) and H (2), is reported, involving asymmetric reduction of alkynones 3 and 4, respectively, with the Corey BakshiSibata (CBS) catalyst as a key step (Scheme 3), 3 and 4 being obtained from a common intermediate, the chiral alkynol 12 (Scheme 2).
