  • Synthesis of the Spatane Nucleus (<i>cis</i>-<i>anti</i>-<i>cis</i>-tricyclo[5.3.0.0<sup>2,6</sup>]decane) using the Pauson−Khand Reaction with a Remarkable Reversal in Regioselectivity
    作者:Bruce A. Kowalczyk、Timothy C. Smith、William G. Dauben
    DOI:10.1021/jo9708194
    日期:1998.3.1
    The Pauson-Khand reaction of cyclobutenes 3-5 with a variety of acetylenes yielded cis-anti cis-tricyclo[5.3.0.0(2,6)] decanes 9-17. The unwanted regioisomers 9a and 10a were the sole products using acetylene, but there was a remarkable reversal in orientation of the cyclobutene component yielding the desired regioisomer 13b upon using (trimethylsilyl)acetylene. The importance of the allylic methyl group in the cyclobutenes in directing the regiochemical outcome was substantiated by the lack of selectivity in Pauson-Khand reactions of desmethylcyclobutene 5 with acetylene and (trimethylsilyl)acetylene. The relative unimportance of electronic control of regiochemistry was concluded from the consistent ratio of Pauson-Khand reaction products from norbornenone 22 with various acetylenes. A hypothesis rationalizing the regiochemical outcome was based on steric interactions of the allylic methyl roup from the cyclobutene component with either the smaller acetylene substituent or the CO ligands on the cobalt. This steric interaction was further hypothesized to be influenced by the larger acetylene substituent sterically crowding the CO ligands on the cobalt.

  • Total Synthesis of (13Z)-Spata-13(15),17-diene, and the Formal Synthesis of Spatol
    作者:William G. Dauben、Bruce A. Kowalczyk
    DOI:10.1016/s0040-4039(00)94587-8
    日期:1990.1
    The total synthesis of (13Z)-spata-13(15),17-diene was achieved starting from 3-methyl-2-cyclopentenone (6) in 11 steps. The nucleus was constructed in novel fashion using a Pauson-Khand reaction of cyclobutene 9 with trimethylsilylncctylene. The appropriate sidechains were attached in a stereospecific manner taking advantage of the shape of the nucleus.
