Metal nitrite: A powerful oxidizing reagent
Baidya, Mahiuddin,Yamamoto, Hisashi
supporting information; body text, p. 13880 - 13882 (2011/10/09)
An efficient and simple source of nitroso reagents and their oxidation reactions are described. The combination of a Lewis acid and a metal nitrite was applied to the oxidation of silyl enol ethers. Amino acid and peptide derivatives were easily accessed through in situ C-C bond cleavage of fully substituted silyl enol ethers upon oxidation.
Regioselective synthesis and acylation of cyclic bis-(trimethylsiloxy)- 1,3-dienes - New and versatile 1,3-dianion synthons
Langer, Peter,Schneider, Toni
, p. 497 - 500 (2007/10/03)
Cyclohexanone-derived bis-(trimethylsiloxy)-1,3-dienes were regioselectively prepared by the use of different silylating systems. These dienes represent new and versatile 1,3-dianion synthons in Lewis-acid catalyzed acylation reactions.
An Annelation Approach to the Synthesis of Eudesmane and Elemane Sesquiterpene Lactones. Total Synthesis of dl-Dihydrocallitrisin, dl-7,8-Epialantolactone, dl-7,8-Epiisoalantolactone, and dl-Atractylon

An annelation approach to the synthesis of eudesmane sesquiterpenes is described.The 1,6-annelation reagent α-carbomethoxy-β-methyl-γ-methylidene-Δα,β-butenolide (1) is used to construct the linear tricyclic lactone 2,5,6,7,8,8a,9,9aβ-octahydro-8aβ-methyl-2-oxonaphthofuran-3-carboxylic acid methyl ester (2).The conversion of 2 to dl-dihydrocallitrisin (3), dl-7,8-epialantolactone (4), dl-7,8-epiisoalantolactone (5), and dl-atractylon (6) is detailed.Studies directed toward synthesis of the elemane sesquiterpene lactones vernomenin and vernolepin also are presented.
