  • Studies on the Synthesis of Chlorothricolide:  Diastereo- and Enantioselective Syntheses of Model Top-Half Spirotetronate Units
    作者:William R. Roush、Richard J. Sciotti
    DOI:10.1021/jo980379w
    日期:1998.8.1
    Highly enantio- and diastereoselective syntheses of spirotetronates 9 and 10, corresponding to the top-half fragment of chlorothricolide, are described. Key steps in these syntheses are the Diels-Alder reactions of trienes 11 and 12 with the chiral dienophile (R)-6 that provide cycloadducts 18 and 38 with remarkably high stereoselectivity. These reactions exhibit exquisite regioselectivity for addition across the trisubstituted C(18)-C(21) diene unit; they also proceed with remarkable orientational control of the dienophile with respect to the C(18)-C(21) diene, as well as with excellent exo diastereofacial selectivity on the part of the chiral dienophile, (R)-6. Results are presented indicating that it is not necessary to control the stereochemistry of the C(20)-C(21) trisubstituted olefin of the triene precursors, as this unit :readily isomerizes under the conditions of the Diels-Alder reaction. Remarkably, the seemingly unreactive (E,E,E)-triene isomers (E,E,E)-11 and (E,E,E)-12 can be used as the starting material for the Diels-Alder reactions, and the desired exo-cycloadducts 18 and 38 are still obtained in good yield, without products of competitive Diels-Alder reactions of the disubstituted C(16)-C(19) dienes being observed.
