Resumen: 1-epigallicin 11 underwent biomimetic cyclization to trans-(1β-H,5α-H)-guaianolide 22,the stereoespecificity of this cyclization being credited to the fact that it took place via the reacting TC conformation 27. The epimeric nor-guaianolides 15 and 17 were prepared and their rearrangements studied. The biogenetic implications of these processes are discussed.
