چکیده
An iridium-catalyzed asymmetric hydrogenation/oxidative fragmentation of 6-substituted 5H-benzo[d] benzofuro[3,2-b]azepines has been developed, providing an efficient access to optically active 4-substituted 4,5-dihydro-1H-benzo[d]azepin-1-ones with up to 91% ee. A possible reaction pathway includes the asymmetric hydrogenation to furnish chiral cyclic amines and oxidative fragmentation under an air atmosphere.

Synthesis and In Vitro Cytotoxic Activity of Novel [1,3] Dioxolo[4,5-g]Chromen-8-ones as a Chalcone-Like Agent
In this investigation, new structures based on homoisoflavonoids were designed. Homoisoflavonoids are considered as an important class of flavonoids with various biological properties such as cytotoxicity. A new series of benzylidene-6,7-dihydro-8H-[1,3]dioxolo[4,5-g] chromen-8-one derivatives were developed and their cytotoxic activities evaluated for all compounds on three human breast cancer...

Densely functionalized 3-(4-chlorophenyl)-5-(3-hydroxy-4-etoxyphenyl)-4,5-dihydro-1H-pyrazole-1-carboxamide was synthesized in an expedient manner through specification and transamidation respectively, of ester-functionalized pyrazoles. This synthetic protocol allowed for three diversifying steps in which appendages on the pyrazole scaffold were adjusted to optimize inhibition of protein kina...

[formula: see text] A new chiral phosphine, (R,R)-1,2-bis[(R)-4,5-dihydro-3H-dinaphtho[2,1- c:1',2'-e]phosphepino]benzene [abbreviated as (R,R)-binaphane] was prepared on the basis of a practical route from a readily accessible enantiomerically pure binaphthanol. This ligand possesses both binaphthyl chirality and phospholane functionality. Excellent enantioselectivities (95-99.6% ee) have been...
متن کاملSynthesis of 4-amino-4,5-dihydro-1H-1,2,4-triazole-5-ones and their isatin-3-imine derivatives.
Iminoester hydrochlorides 1 have been synthesized. These compounds were then converted into ester ethoxycarbonyl hydrazones 2, from which in turn a new series of substituted 4-amino-4,5-dihydro-1H-1,2,4-triazole-5-ones, 3, was then prepared. Finally a set of isatin imine derivatives 4 was obtained from the reaction of compounds 3 with isatin. The structures of all the new synthesized compounds ...
