Novel Total Synthesis of Mansouramycin B

A novel total synthesis of Mansouramycin B (1) was performed via 10 steps in 28% overall yield starting from the readily available and cheap salicylaldehyde. Two key steps of this total synthesis are noteworthy. The first one is base-promoted one-pot aerobic aromatization of N-tosyltetrahydroisoquinoline 6, the second one is oxidation of 5-hydroxy-3-methyl-isoquinoline 8 with iodobenzene diacetate [PhI(OAc)(2)].

Hendersine A, a novel isoquinoline alkaloid from Corydalis hendersonii

A pair of enantiomeric alkaloids, (+/-) hendersine A (la and lb), featuring an unprecedented couple pattern of an isoquinoline and a succinic acid derivative, a new isoquinoline hendersine B (2), and a known (+)-magnoflorine (3) were isolated from the EtOH extract of Corydalis hendersonii. Their structures were elucidated on the basis of spectroscopic data including HRESIMS, NMR, and experimental and calculated electronic circular dichroism (ECD). Compound 3 exhibited strong inhibitory effects against Ca2+ overload in glutamate-induced PC12 cells. Compounds 1-3 exhibited a protective effect against H9c2 myocyte injuries induced by LPS-stimulation conditioned medium. (C) 2016 Elsevier Ltd. All rights reserved.

One-pot two-step tandem reactions for selective synthesis of pyrrolo[2,1-a]isoquinolines and dihydro-, tetrahydro-derivatives

A sequential one-pot two-step tandem reaction for selective and efficient synthesis of pyrrolo[2,1-a]isoquinoline and its dihydro- and tetrahydro-derivatives has been developed. The tandem reactions of isoquinoline, a-halogenated methylene compounds, aromatic aldehydes, and cyanoacetamide firstly give tetrahydropyrrolo[2,1-a]isoquinolines as main products. The corresponding pyrrolo[2,1-a]isoquinolines and dihydropyrrolo[2,1-a]isoquinolines can be obtained directly by controlling oxidation with DDQ. The mechanism of this tandem reaction involved the 1,3-dipolar cycloaddition of isoquinolinium ylide as the key step. A unique elimination of the amido group preferring to the cyano group has been observed. (C) 2011 Elsevier Ltd. All rights reserved.

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.

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.

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.

Cathodic electrochemical regiospecific hydroxylation of isoquinoline and quinoline via their carboxylic acids

A new electrochemical regiospecific hydroxylation reaction with application to some aromatic benzopyridines is described. This hydroxylation is carried out by electrochemical reduction of isoquinoline or quinoline carboxylated derivatives at graphite electrode and in presence of water. The most important feature of this new process is that only one hydroxylated product is obtained from each carboxylated derivative. Three hydroxy derivatives of isoquinoline and quinoline have been obtained with moderate yields, between 45% and 73%. A plausible reaction route is proposed for the electrochemical process.
