Design and synthesis of violet odorants with bicyclo[6.4.0]dodecene and bicyclo[5.4.0]undecene skeletons
Kraft, Philip
, p. 695 - 703 (2007/10/03)
The Diels-Alder reaction of 1,2-bis(methylene)cyclooctane (13), 4- methylenespiro[2.7]decane (29), 4-methylenespiro[2.6]nonane (40) and 4- methylenespiro[2.7]dec-8-ene (46) with different α,β-unsaturated carbonyl compounds afforded various derivatives 16, 18, 20, 22, 24, 26, 32, 36, 38, 41, 42 and 47 of a molecular-modeled lead compound 9. These less flexible β- ionone-mimics with bicyclo[6.4.0]dodecene and bicyclo[5.4.0]undecene skeletons possess interesting fruity-woody-floral odor notes and provide insight into the structure-odor correlation of violet odorants. 5-(2- Methylcycloalk-1-en-1-yl)hex-3-en-2-ones (e.g. 35) were identified as byproducts of the Rh(I)-catalyzed reactions of the vinylcyclopropanes 29 and 40.
Reactions of 2-Chloroethyl sulfides: III. Mechanism of methanolysis of 2-Chloroethyl sulfides
Fomina,Vishnyakov,Glushkov
, p. 1282 - 1288 (2007/10/03)
The products and kinetics of methanolysis of 2-chloroethyl methyl sulfide, 2-chloroethyl 2-methoxyethyl sulfide, 2,2′-dichlorodiethyl sulfide, and 2-chloroethyl phenyl sulfide (at a concentration of 0.05-0.2 M) were studies by 13C NMR spectroscopy and gas-liquid chromatography. The rate of methanolysis decreases in the following series: methyl > methoxyethyl > 2-chloroethyl > phenyl. The amount of sulfonium dimers among the products decreases in the same series; the rate of dimerization of 2-chloroethyl methyl sulfide exceeds the rate of methanolysis. The reaction of 2-chloroethyl sulfides in methanol with a strong neutral nucleophile, thiourea, is of the second order. The rate constants of this reaction show a correlation with the constants σ* of substituents on the sulfur, which is similar to that found for the hydrolysis. This correlation indicates formation of intermediate ethylenesulfonium ion. Unlike the hydrolysis process, the rate-determining stage in the methanolysis is the reaction of ethylsulfonium ion with the nucleophile rather than ionization of 2-chloroethyl sulfide.
Synthesis of mitomycin and its analogs
-
, (2008/06/13)
The present invention relates to the synthesis of mitomycin and analogs thereof that are useful as anticancer antibiotics. The invention further relates to analogs of mitomycin, which can be prepared according to the methods of synthesis provided. The synthetic method of the invention provides for reacting a derivitized indole with a dialkylvinylsulfonium salt to yield a tricyclic skeleton having the precursors of the fourth ring in one step, followed by an oxidation step or steps to close the fourth ring and prepare mitomycin or a related compound.

Ruder, Suzanne M.,Ronald, Robert C.
, p. 5501 - 5504 (2007/10/02)
Ketones are readily spiroannelated by 2-chloroethyldimethyl sulfonium iodide 1 in the presence of t-butoxide anion in t-butanol.The procedure affords a simple one step spirocyclopropanation of ketones in good yields.
