Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5-Methylfuran-2(3H)-one, is researched, Molecular C5H6O2, CAS is 591-12-8, about Catalyst-controlled regioselective nitrosocarbonyl aldol reaction of deconjugated butenolides.Formula: C5H6O2.

An unprecedented regiodivergent nitrosocarbonyl aldol reaction of γ-substituted deconjugated butenolides was described. While Lewis base catalyst quinidine leveraged O-selective nitrosocarbonyl aldol reaction exclusively at the γ-position of deconjugated butenolides to produce γ-substituted-butenolides I [R = Me, n-Pr, PhCH2, etc.; R1 = t-BuO, OCH2CH=CH2, PhCH2O, 4-MeC6H4, etc.], Lewis acid catalyst Cu(OTf)2 steered the competitive N-selective nitrosocarbonyl aldol reaction at the β-position, resulting in hetero-β,γ-difunctionalized-butenolides II [R2 = Me, Ph, 4-MeC6H4CH2, PhCH2; R3 = t-Bu, PhCH2, 1-naphthyl, etc.]. Both processes were amenable to a broad range of substrates and scalable, while the latter one represented a rare example of one-pot hetero-β,γ-difunctionalization of butenolide scaffolds.

Total twenty-five 7-formyl-naphthyridyl-urea derivatives were designed, synthesized and evaluated for their inhibition of FGFR4 kinase and antitumor activity. The pharmacol. data indicated that most of the tested compounds showed high selectivity towards FGFR4 kinase and could significantly inhibit FGFR4 and the tumor cells lines with the high expression of FGFR4. In particular, compounds 6f, 6g, 6h, 6l, 6m and 6s showed a good performance in pharmacokinetic tests. When tested in mice, the representative compound 6f was found to have good pharmacokinetic parameters, low toxicity, and better tumor inhibiting activity in vivo.

SDS of cas: 18436-73-2. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 4-Chloro-8-methylquinoline, is researched, Molecular C10H8ClN, CAS is 18436-73-2, about Human α1-adrenoceptor subtype selectivity of substituted homobivalent 4-aminoquinolines.

A series of ring-substituted ethyl- and heptyl-linked 4-aminoquinoline dimers were synthesized and evaluated for their affinities at the 3 human α1-adrenoceptor (α1-AR) subtypes and the human serotonin 5-HT1A-receptor (5-HT1A-R). We find that the structure-specificity profiles are different for the two series at the α1-AR subtypes, which suggests that homobivalent 4-aminoquinolines can be developed with α1-AR subtype selectivity. The 8-Me ethyl-linked analog has the highest affinity for the α1A-AR, 7 nM, and the greatest capacity for discriminating between α1A-AR and α1B-AR (6-fold), α1D-AR (68-fold), and the 5-HT1A-R (168-fold). α1B-AR selectivity was observed with the 6-Me derivative of the ethyl- and heptyl-linked 4-aminoquinoline dimers and the 7-methoxy (7-OMe) derivative of the heptyl-linked analog. These substitutions result in 4- to 80-fold selectivity for α1B-AR over α1A-AR, α1D-AR, and 5-HT1A-R. In contrast, 4-aminoquinoline dimers with selectivity for α1D-AR are more elusive, since none studied to date has greater affinity for the α1D-AR over the other two α1-ARs. The selectivity of the 8-Me ethyl-linked 4-aminoquinoline dimer for the α1A-AR, and 6-Me ethyl-linked, and the 6-Me and 7-OMe heptyl-linked 4-aminoquinoline dimers for the α1B-AR, makes them promising leads for drug development of α1A-AR or α1B-AR subtype selective ligands with reduced 5-HT1A-R affinity.

Compound: 4-Chloro-8-methylquinoline, is researched, Molecular C10H8ClN, CAS is 18436-73-2, about Cp*CoIII-Catalyzed Alkylation of Primary and Secondary C(sp3)-H Bonds of 8-Alkylquinolines with Maleimides. Author is Kumar, Rakesh; Kumar, Rohit; Chandra, Devesh; Sharma, Upendra.

The cobalt(III)-catalyzed C(sp3)-H bond alkylation of 8-Me quinoline with maleimides is reported. In contrast to the rhodium-catalyzed method, in the current cobalt-catalyzed method, a catalytic amount of acid is used, and importantly, it is also applicable to secondary C(sp3)-H bond alkylation. The developed methodol. is applicable for N-alkyl- and N-aryl-substituted maleimides and unsubstituted maleimides, and it also tolerates the variety of functional groups on the 8-Me quinoline moiety. Atom-economy and high regioselectivity with good to excellent yields of the alkylated products under mild reaction conditions are important features of this method.
