Acetoxymaleic Anhydride as Ketene Equivalent in the Diels-Alder Reaction
CHIMIA, 1992 Acetoxymaleic anhydride (AMA) has been shown to be a versatile ketene equivalent in the Diels-Alder reaction for the conversion of 1,3-dienes into cyclohexanones.

Enantioselective synthesis of highly functionalised cyclohexanones starting from R-(-)-Carvone.
, 1998 Copper (I) catalysed conjugate addition of methylmagnesium iodide to R-(−)-carvone and trapping the enolate as its trimethylsilyl enol ether, followed by a trityl perchlorate (TrClO4) catalysed Mukaiyama-aldol reaction, is an efficient method for the ...

Synthesis of Novel Heteroaryl Iodonium Salts and Enantioselective a-Arylation of Cyclohexanones
, 2006 We have developed a direct arylation reaction of cyclohexanones employing diaryl iodonium(Ill) salts as electrophiles. The reaction was made enantiosilective by the use of a chiral base, resultinginZ,4-disubstituted cyclohexanones in high yields and with

Cyclohexanones by Rh-Mediated Intramolecular C–H Insertion
, 2016 Some long chain α-aryl α-diazo ketones under Rh catalysis cyclize efficiently to the corresponding cyclohexanones. This is in marked contrast to the cyclizations of α-diazo β-ketoesters, which consistently deliver cyclopentanone ...

Photostability of Cyanine Dyes and Its Correlation to Their Photothermal and Photodynamic Effects
Chemistry – A European Journal, EarlyView.Photostability (PS) of dyes is a crucial parameter for performance in biological applications, yet often underrated. Here PS of several cyanines is investigated. The method is carefully evaluated and designed as a general and easy tool to compare PS of NIR dyes.
