Reactions of 3-formylchromone with active methylene and methyl compounds and some subsequent reactions of the resulting condensation products.
This review presents a survey of the condensations of 3-formylchromone with various active methylene and methyl compounds, e.g. malonic or barbituric acid derivatives, five-membered heterocycles, etc. The utilisation of the condensation products for the synthesis of different heterocyclic systems, which is based on the ability of the gamma-pyrone ring to be opened by the nucleophilic attack is ...
متن کاملRegio- and stereoselective reactions of a rhodanine derivative with optically active 2-methyl- and 2-phenyloxirane
The reaction of a rhodanine derivative (= (Z)-5-benzylidene-3-phenyl-2-thioxo-1,3-thiazolidin4-one; 1) with (S)-2-methyl-oxirane (2) in the presence of SiO2 in dry CH2Cl2 for 10 days led to two diastereoisomeric spirocyclic 1,3-oxathiolanes 3 and 4 with the Me group at C(2) (Scheme 2). The analogous reaction of 1 with (R)-2-phenyloxirane (5) afforded also two diastereoisomeric spirocyclic 1,3ox...
متن کاملDomino reactions of 2-methyl chromones containing an electron withdrawing group with chromone-fused dienes.
Domino reactions of 2-methyl substituted chromones containing an electron withdrawing group at the 3-position with chromone-fused dienes synthesized a diverse range of benzo[a]xanthones and complicated chromone derivatives. These multiple-step reactions result in either two or three new C-C bonds without a transition metal catalyst or an inert atmosphere.
متن کاملAlternansucrase acceptor reactions with methyl hexopyranosides.
Alternansucrase (EC 2.4.1.140, sucrose: (1-->6), (1-->3)-alpha-D-glucan 6(3)-alpha-D-glucosyltransferase) is a D-glucansucrase that synthesizes an alternating alpha-(1-->3), (1-->6)-linked D-glucan from sucrose. It also synthesizes oligosaccharides via D-glucopyranosyl transfer to various acceptor sugars. We have studied the acceptor products arising from methyl glycosides as model compounds in...
متن کاملReactions of 1-methyl-2-mercaptoimidazole with hypochlorous acid and superoxide.
Reactions of thioureylene antithyroid drugs (1-methyl-2-mercaptoimidazole and carbimazole) with hypochlorous acid (HOCl) and superoxide were followed optically and products were analyzed by mass spectrometry. 1-methyl-2-mercaptoimidazole (MMI) and carbimazole reacted rapidly with HOCl with a rate constant of 1 x 10(7) and 7 x 10(6) M(-1)s(-1), respectively. The characteristic spectrum assigned ...
