OXIDATION OF ARYL ALKYL KETONES TO ALPHA-ACYLOXY, ALPHA-(CAMPHORSULFONYLOXY), OR ALPHA-HYDROXY DERIVATIVES USING MANGANESE(III) ACETATE IN COMBINATION WITH CARBOXYLIC-ACIDS OR (1S)-(+)-10-CAMPHORSULFONIC ACID
DEMIR, AS; CAMKERTEN, N; AKGUN, H; Tanyeli, Cihangir; MAHASNEH, AS; WATT, DS (Informa UK Limited, 1990-01-01)
The α-oxidation of aryl alkyl ketones using manganese(III) acetate in the presence of various carboxylic acids and (1S)-(+)-10-camphorsulfonic acid provided a convenient synthesis of α-acyloxy, α-(10-camphorsulfonyloxy), and α-hydroxy derivatives in good yield.
Synthesis of chiral lactones via the baeyer villiger oxidation of cyclic aromatic acetoxy ketones novel annulation reactions of 2-propynyl-1,3-dicarbonyl compounds to form pyrroles addition of acyl phosphonates to diethyl cyanophosphonate (depc)
Aybey, Asuman; Demir, Ayhan Sıtkı; Department of Chemistry (2009)
Chiral Baeyer-Villiger (BV) oxidation of cyclic ketones allows rapid access to asymmetric lactones as valuable intermediates in organic chemistry and frequently encountered precursors in enantioselective synthesis. In the first part, BV oxidation of functionalized ketones, especially cyclic -hydroxy and acetoxy ketones is described which could be a straightforward route to the -hydroxy lactones and -hydroxyalkanoic acid derivatives. The -acetoxylation of indanone, tetralone and chromanone derivatives by usi...
Synthesis of ferrocenyl cycloheptadienones
Açıkgöz, Canet; Zora, Metin; Department of Chemistry (2005)
Synthesis of seven-membered ring systems such as cycloheptadienones has attracted a great deal of attention in organic chemistry since they are present in a variety of biologically important molecules. Incorporation of the essential structures of such compounds with a ferrocene moiety instead of an aryl group could provide subtances with enhanced antitumor activities since some ferrocene derivatives have already proved to be active against a number of tumors. To develop a ferrocenyl-substituted seven-member...
Synthesis of 1,2-amino alcohols having tertiary acohol moietry
Sümer, Burak; Tanyeli, Cihangir; Department of Chemistry (2006)
An applicable method for the racemic synthesis of 1,2-amino alcohols having tertiary alcohol moiety was developed. This method can be used as a general method for the synthesis of various 1,2-amino alcohols with various tertiary alcohol moieties by changing chloroacetone with different monohalo ketones, and with different aryl halides or alkyl halides. The resultant racemic 1,2-aminoe alcohols were tried to resolve by using various hydrolase type enzymes under different conditions by changing the parameters...
Synthesis of 5-ferrocenyl-4-((4-nitrophenyl)sulfenyl)-1H-pyrazoles by electrophilic cyclization
Karahan Dağ, Fulya; Zora, Metin; Department of Chemistry (2011)
Pyrazoles have been intensely studied in the design and synthesis of biologically active agents because they display considerable medicinal activities. Recent studies have shown that integration of a ferrocenyl unit with structural features of pyrazoles can result in the formation of the new products with enhanced or/and unexpected biological activity since several ferrocene derivatives have already been illustrated to be active against a number of tumors. Therefore, we have investigated the electrophilic c...
