Construction of Spiropyrido[2,1-a]isoquinoline via Tandem Reactions of Huisgen’s 1,4-Dipoles with Various Alkene Dipolarophiles

The three-component reaction of isoquinoline, dimethyl acetylenedicarboxylate and arylidene pivaloylacetonitrile in acetonitrile at room temperature afforded pyrido[2,1-a]isoquinolines 1a-1j in good yields and with high diastereoselectivity. When arylidene-substituted 1,3-indanediones, Meldrum acids, and N,N’-dimethylbarbituric acids were employed in the reaction, the novel functionalized spiro[indene-2,1-pyrido[2,1-a]isoquinolines] 2a-2j, spiro[pyrido[2,1-a]isoquinoline-1,5-[1,3]dioxanes] 3a-3h and spiro[pyrido[2,1-a]isoquinoline-1,5-pyrimidines] 4a-4e were also efficiently synthesized in satisfactory yields. The reaction mechanism included domino formation of Huisgen’s 1,4-dipole, Michael addition and cyclization processes.

Stress-related polyketide metabolism of dioncophyllaceae and ancistrocladaceae

The discovery of a novel biosynthetic pathway to isoquinoline alkaloids is described. The naphthylisoquinoline alkaloid dioncophylline A, one of the most prominent representatives of a new class of structurally and pharmacologically intriguing secondary metabolites, is shown to originate from acetate units, both molecular halves, the isoquinoline part and the naphthalene portion, being formed from identical polyketide precursors. All other tetrahydroisoquinoline alkaloids previously investigated, ultimately originate from aromatic amino acids. The novel pathway to isoquinoline alkaloids (hence acetogenic) was proved by feeding experiments with C-13-labelled precursors administered to callus cultures of Triphyophyllum peltatum (Dioncophyllaceae), followed by NMR investigations using the potent cryoprobe methodology. The new pathway is largely stress-sensitive: upon exposure to chemical, biotic or physical stress, T. peltatum stops producing the isoquinoline part, so that the naphthalene moiety accumulates in the chemical form of naphthoquinones like plumbagin and droserone and the chiral tetralone isoshinanolone.

SYNTHESIS AND PHYSICAL-PROPERTIES OF AMORPHOUS POLY(ARYL ETHER ISOQUINOLINE)S

The synthesis of a new class of N-heterocyclic polymers, the poly(aryl ether isoquinoline)s, is described via an intramolecular ring-closure reaction of poly(aryl ether ketone)s containing the o-dibenzoylbenzene moiety with benzylamine in the presence of 1,8-diazabicyclo[5.4.0]undecene (DBU) in refluxing chlorobenzene. The synthesis of copolymers of poly(aryl ether ketone)s and poly(aryl ether isoquinoline)s is demonstrated, and the copolymer contents were determined by H-1 NMR studies. Ring-closure reactions of previously prepared end-capped poly(aryl ether ketone)s to poly(aryl ether isoquinoline)s were done to determine exact molecular weights of the resulting polymers. Various fluoro-substituted isoquinoline monomers were prepared and polymerized with bisphenols in N-methylcaprolactam (NMC) in the presence of excess base (K2CO3). The high molecular weight polymers showed T(g)’s ranging from 225 to 320-degrees-C. Studies by TGA showed polymer 5% weight losses in air and nitrogen above 500-degrees-C.

REACTIONS OF 2H,5H-IMIDAZO[1,5-B]ISOQUINOLINE-1,3-DIONES WITH BROMINE

Treatment of 2H,5H-imidazo[1,5-b]isoquinoline-1,3-diones 1 with one molar proportion of bromine in glacial acetic acid gave complex mixtures. The major component of each mixture was the corresponding 1,3-dioxoimidazo[1,5-b]isoquinolinium bromide 4; other constituents shown to be present included the 1,3-dioxo-10-bromoimidazo[1,5-b]isoquinoliniumbromides5,2H,5H-imidazo[1,5-b]isoquinoline-1,3-diones 3, isocarbostyryl derivatives 9, dihydroisocarbostyryl derivatives 10, and 3-carbamoyl-isoquinolines 8. Reaction of the 2H,5H-imidazo[1,5-b]isoquinoline-1,3-diones 1 in glacial acetic acid with excess of bromine afforded 1,3-dioxo-10-bromoimidazo[1,5-b]isoquinolinium bromides 5 as principal products. Bromination of compounds 1 in carbon tetrachloride yielded mainly 1,3-dioxo-2H-imidazo[1,5-b]isoquinolinium bromides 12.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Tetraethylammonium dichlorido[N,N ‘(o-phenylene)bis(isoquinoline-2-carboxamidato)-kappa N-4]cobaltate(III)

In the title compound, (C8H20N)[Co(C26H16N4O2)Cl-2], the four N atoms of the N,N’-(o-phenylene)bis(isoquinoline-2-carboxamidate) (biqb(2-)) ligand form the equatorial plane of a distorted octahedral coordination environment around the Co-III ion, while two chloride ligands are axially coordinated. The Co-N-amide distances are significantly shorter than the Co-N-pyridyl distances. The dihedral angle between the two isoquinoline fused-ring systems is 25.72 (7)degrees. The crystal structure is stabilized, in part, by intermolecular C-cation-H center dot center dot center dot Cl and C-isoquinoline- H center dot center dot center dot Cl hydrogen bonds.

Strategies and Synthetic Methods Directed Toward the Preparation of Libraries of Substituted Isoquinolines

Strategies for the production of substituted isoquinoline libraries were developed and explored. Routes involving microwave-assisted variants of the Bischler-Napieralski or Pictet-Spengler reaction allowed for cyclization of substituted beta-arylethylamine derivatives. The dihydroisoquinolines and tetrahydroisoquinolines thus generated could then be oxidized to their corresponding isoquinoline analogues. An alternate strategy, however, involving the preparation and activation of isoquinolin-1(2H)-ones is demonstrated to be a more practical, rapid, and efficient route to C1- and C4-substituted isoquinoline libraries.
