Fe-Catalyzed Cycloisomerization of Aryl Allenyl Ketones: Access to 3-Arylidene-indan-1-ones

A cycloisomerization of aryl allenyl ketones to 3-arylidene-indan-1-ones using a cationic Fe-complex as a catalyst is reported. The catalyst opens a synthetically interesting reaction pathway to this surprisingly underrepresented class of indanones that are not accessible using alternative catalytic systems.

The Cs2CO3-Catalyzed Reaction of 2-Oxindoles with Enones for the Preparation of Indolin-3-Ones and Their Further Transformation

The Cs2CO3-catalyzed reaction of 2-oxindoles with enones affords 2,2-disubstituted indolin-3-ones through domino “Michael addition-oxidation-ring-cleavage-C-N coupling” process. O2 acts as the sole oxidant to accomplish th

Successively recycle waste as catalyst: A one-pot wittig/1,4-reduction/paal-knorr sequence for modular synthesis of substituted furans

A one-pot tandem Wittig/conjugate reduction/Paal-Knorr reaction is reported for the synthesis of di- or trisubstituted furans. This novel sequence first demonstrates the possibility of successively recycling waste from upstream steps to catalyze downstream reactions.

Synthesis of cyclic nitrone and 1,2-oxazine from 1,2,4-triaryl-but-2-ene-1, 4-dione and hydroxylamine

The reaction of hydroxylamine hydrochloride with differently substituted phenyldibenzoylethylene has been investigated. Both cyclic nitrone and 1,2-oxazine have been isolated and characterized by one- and two-dimensional NMR data and also by single crysta

Reaction of furans with trithiazyl trichloride: A new synthesis of isothiazoles

Trithiazyl trichloride 1 converts 2,5-diphenylfuran into 5-benzoyl-3-phenylisothiazole 2 regiospecifically and in high yield. This is a new ring opening of furans and a new synthesis of isothiazoles. 2,5-Bis(4-methylphenyl)furan, 3-bromo-2,5-diphenylfuran, 2,3,5-triphenylfuran, 2,5-di-tert-butylfuran and its 3-chloro and 3-bromo derivatives react in an entirely analogous manner to give the corresponding isothiazoles (55-85%) in synthetically useful, one-pot, conversions. 2,5-Diphenylthiophene reacts more slowly with the trimer 1 to give the same product, 2, as the corresponding furan, probably by oxidation of the analogous thiobenzoyl compound by the reagent, which is shown to oxidise thiobenzophenone to benzophenone very rapidly. Tetraphenylcyclopentadienone 8 reacts rapidly with the trimer to give 3,4,5,6-tetraphenyl-2(1H)-pyridone 10 (56%). Possible mechanisms in which the monomer, Cl-S≡N, is the reacting species are proposed for all of these reactions.
