title: First total synthesis of trans- and cis-resorcylide: remarkable hydrogen-bond-controlled, stereospecific ring-closing metathesis.
abstract: [reaction: see text] Stereospecific synthesis of the pair of natural macrolides, trans- and cis-resorcylide, was performed using ring-closing metathesis on dienes 3 and 4, which lack or feature an intramolecular H-bond, respectively. An effective Stille carbonylative coupling of benzyl chlorides 11 and 15 was employed for their preparation. The influence of intramolecular H-bonding on the interconversions of resorcylides was also studied.
