B. Travis et B. Borhan, Oxidative cyclization of 1,4-dienes to yield 2,3,5-trisubstituted tetrahydrofuran-diols, TETRAHEDR L, 42(44), 2001, pp. 7741-7745
KMnO4 and OsO4 catalyze the oxidative cyclization of 1,4-dienes to provide
2,3,5-trisubstituted tetra hydrofuran-diols in 30%, yield. This reaction pr
oceeds stereoselectively via a proposed [3+2] cycloaddition. Competing oxid
ative pathways are the major non-productive processes that reduce the yield
of the reaction, however, four stereogenic centers are established in one-
step. (C) 2001 Elsevier Science Ltd. All rights reserved.
