scheme or table, p. 217 - 221 (2009/04/06)
Enamination of a wide variety of primary amines was successfully described with excellent chemoselectivity in the presence of catalytic amounts of β-cyclodextrin in water under mild conditions. Aliphatic amines also reacted efficiently to produce the corresponding enaminones.

Enamination of a wide variety of primary amines was successfully carried out in the presence of catalytic amounts of bismuth(III) trifluoroacetate immobilized on molten tetrabutylammonium bromide as "green" media under mild conditions. This new system of the catalyst is recyclable and reusable. Generally, the results of the reaction in tetrabutylammonium bromide is better than the previously obtained results in water because of their yields and reaction times.
Cerium(III) chloride heptahydrate (CeCl3·7H2O) as an efficient enamination catalyst in aqueous media
Khodaei,Khosropour,Kookhazadeh
, p. 1445 - 1448 (2007/10/03)
Cerium(III) chloride heptahydrate CeCl3·H2O catalyzes enamination of β-dicarbonyl compounds with primary amines in aqueous medium at room temperature to afford the corresponding β-enamino ketones with high chemoselectivity.

In an extension of our work in the held of nitrogen heterocycles with potential cytotoxic activity, the synthesis of some substituted 4-chloro-3- (2-chloroethyl)-2-methylquinolines (10-13) from their parent 3-[l- (phenylamino)ethylidene]-dihydro-2(3H)-furanones (6-9) is reported. The conversion of 10-13 to some thieno-, furo- and pyrrolo[3,2-c]quinolines (14- 27, 31-33) is also described. The compounds were evaluated for their toxicity in brine shrimp (Artemia salina), and their cytotoxicity against some clinically isolated human tumors in vitro. Several compounds exhibited good toxic activity against Artemia salina, while the furanone (6, NSC 680781) displayed good antineoplastic activity and high selectivity against some cell lines from leukemia, lung cancer, colon and melanoma panels. This compound has been selected by the NCI for further testing in a new in vivo anticancer hollow fiber assay.
