The totalsynthesis of a methylated analogue of (+)-Salvianolic acidC has been achieved. Key aspects of the synthetic route include an economical Cu(I) acetylide coupling, unique carboxyl activation conditions via microwave irradiation and a novel lipase catalysed kinetic resolution of a racemic mixture of secondary alcohol Danshensu. The preparation of this methylated analogue will not only improve
