摘要:
AbstractThe photolysis of anhydro‐4‐hydroxy‐2,3,5‐triphenylthiazolium hydroxide and of two substituted derivatives in methanol ort‐butyl alcohol in the presence of trimethylphosphite, leads exclusively and stereospecifically to α‐aryl‐β‐anilinocinnamate esters. A mechanism which involves ring contraction to a bicyclic β
