T1 - The biomimetic synthesis of trans-(1β-h,5α-h)-guaianolides LA - eng PY - 1988 SP - 4575 EP - 4584 T2 - Tetrahedron SN - 0040-4020 VL - 44 IS - 14 AB - 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. © 1988.
