Gómez Rodríguez, Mª Ángeles Martínez-Ripoll, Martín Ministerio de Educación y Ciencia (España) Comisión Asesora de Investigación Científica y Técnica, CAICYT (España) Consejo Superior de Investigaciones Científicas (España) 10 pages, 4 figures, 5 tables, 2 schemes. Lists of observed and calculated structure factors, final anisotrooic parameters for heavy atoms, positional and thermal parameters for H-atoms, are available from the Cambridge Crystallographic Data Centre (CCDC), University Chemical Laboratory, Lensfield Road, Cambridge CB2. 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. This work was subsidized in part by the CAICYT, Spain (Grant No 3190/84). MMA and JAP thank the MEC and CSIC, respectively, for research grants. 2009-05-05T09:14:43Z 2009-05-05T09:14:43Z 1988 artículo http://purl.org/coar/resource_type/c_6501 Tetrahedron 44(14): 4575-4584 (1988) 0040-4020 http://hdl.handle.net/10261/12808 10.1016/S0040-4020(01)86160-3 http://dx.doi.org/10.13039/501100007272 http://dx.doi.org/10.13039/501100003339 en http://dx.doi.org/10.1016/S0040-4020(01)86160-3 none 2373 bytes 730058 bytes text/plain application/pdf Elsevier |
