Epidermal growth factor receptor tyrosine kinase: Structure-activity relationships and antitumour activity of novel quinazolines

Investigation of structure-activity relationships of novel quinazolines has identified 4-(4-isoquinolylamino)-quinazoline and a 4-(trans-2-phenylcyclopropylamino)-quinazoline as potent inhibitors of EGF-receptor tyrosine kinase in vitro. Further modificatons of the latter compound have identified a derivative which shows anti-tumour activity against a tumour xenograft model when dosed orally once per day.

Synthesis of fused systems in the isoquinoline series: Oxazolo- and pyrrolo[3,2-c]isoquinolines

In order to synthesize the pyrrolo[3,2-c]isoquinoline structure, three different routes starting from readily available isoquinolines were tried. The ring closure reaction of a malonic derivative of 4-amino-3- bromoisoquinoline led to an oxazolo[3,2-c]isoquinoline instead of the target molecule. This latter was obtained via Sonagashira coupling reaction followed by ring closure under basic conditions. A study of the lithiation of the N- sulfonated pyrrolo[3,2-c]isoquinoline was undertaken. After optimization of the lithiation conditions, various 2-substituted pyrrolo[3,2-c]isoquinolines were obtained and their oxidation reactions studied.

Thermal and Mechanochemical Syntheses of Luminescent Mononuclear Copper(I) Complexes

Mononuclear CuI iodide complexes, [CuI(PPh3)2L] {PPh3 = triphenylphosphine; L = 4-aminoisoquinoline (4-aiq) (2), 5-aminoisoquinoline (5-aiq) (3), and 5-nitroisoquinoline (niq) (4)}, were prepared by three different methods: normally used reactions in the solution state, mechanochemical synthesis, and newly developed solvent-free thermal synthesis. Although no solvent was required for the mechanochemical synthesis of the parent complex [CuI(PPh3)2(iq)] (1; iq = isoquinoline), a minimal amount of assisting solvent (PhCN) was required for the mechanochemical syntheses of the three functionalized isoquinoline complexes. The amino-functionalized isoquinoline complexes were successfully synthesized by heating the ground mixture of three types of starting materials at ca. 100 C, where the PPh3 ligand melted to promote complex formation by acting as the ligand and the solvent. The emission properties strongly depend on the L ligand: Complexes 2 and 3 showed vibronic emission spectra originating from the 3pipi* excited state localized on the L ligand, whereas complex 4 did not show any emission in the visible region.

A Borrowing Hydrogen Strategy for Dehydrative Coupling of Aminoisoquinolines with Benzyl Alcohols in Water

We report a borrowing hydrogen strategy for a palladium-catalyzed dehydrative coupling of aminoisoquinolines with benzylic alcohols in water. This cascade reaction using the pi-benzylpalladium system can be achieved in an atom-economic process without the need for base or other additives, furnishing the N-benzylated aminoisoquinolines in moderate to excellent yields along with water as the sole co-product. The crossover experiment using [D7]benzyl alcohol and 4-methoxybenzyl alcohol afforded H/D scrambled products. KIE experiments showed that benzylic C?H bond cleavage of benzyl alcohol was involved in the turnover limiting step (KIE = 4.4). The coupling reaction was found to be first order in benzyl alcohol with a kinetic solvent isotope effect (KSIE) of 1.6. These experimental results are consistent with a borrowing hydrogen mechanism in water. Notably, the water-soluble Pd0/TPPMS system can be applied to the more challenging catalytic benzylic amination with aminoisoquinoline nucleophiles despite the possible deactivation of PdII species.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 23687-25-4, you can also check out more blogs about23687-25-4
