Rearrangement and radical puzzle: Chiral epoxides, silylated acetamides, and stable radical TEMPO provide, with the help of ferrocenium hexafluorophosphate, dioxygenated carbonylcompounds, which serve as versatile radical cyclization precursors.

A convergent total synthesis of the mono(tetrahydrofuran) annonaceous acetogenin murisolin, with a longest linear sequence of nine steps, is reported. Assembly of the complete carbon framework by crossmetathesis and late-stage tetrahydrofuran formation on the intact backbone are key elements of the synthesis.
An enantioselective total synthesis of Sch-725674 using dithiane alkylation, cross metathesis reaction, Yamaguchi macrolactonization and a substrate controlled stereoselective reduction as key steps is described.
Palladium-catalyzed coupling reactions of bromobenzaldehydes with 3,4-di(tert-butyldimethylsilyloxy)-1-alkene to (3,4-dihydroxyalkenyl)benzaldehydes in the synthesis of lipoxin analogues
o-, m-, and p-(3, 4-Dihydroxyalkenyl)benzaldehydes were selectively prepared via palladium-catalyzed Heck-type coupling reactions of o-, m-, and p-bromobenzaldehydes with 3, 4-di(tert-butyldimethylsilyloxy)-1-alkene. The products were employed for the synthesis of lipoxin analogues, o-, m-, and p-3-hydroxyalkenyl-3, 4-dihydroxyalkenylbenzenes. (C) 1998 Elsevier Science Ltd. All rights reserved.
