Thermolysis of Thiophenedicarboxylic Acid Anhydrides as a Route to Five-Membered Hetarynes

Flow vacuum thermolysis (FVT) of the anhydrides of thiophene-2,3- (5) and -3,4-dicarboxylic acid (6) and of thianaphthene-2,3-dicarboxylic acid (7) in the presence of thiophene, 1,3-cyclohexadiene, or benzene gave thianthrene (15a), presumably by aromatization of an intermadiate Diels-Alder adduct of the diene traps and the aryne 2,3-didehydrothiophene (8).A similar rationale explains the formation of dibenzothiophene from 7 and thiophene, the four monomethylthianaphthenes 22-25 from 5 and cyclopentadiene, 5,6-dimethylthianaphthene (15f) from 5 and 2,3-dimethylbutadiene, and a mixture of hydroxythianaphthenes (15d) from 5 and furan.The latter reaction also produces a mixture of isomeric cyclopentanothiophenes (19) which probably arise by decarbonylation of 15d.An FVT reaction of 5 with propyne as the trap gave a mixture of allenyl-(28) and propynylthiophenes 29 which probably arise by an ene reaction of the trap and the aryne 8.Decomposition of the anhydrides 5 and 6 in molten anthracene led only to Friedel-Crafts products such as thienylanthracenes 33 and quinones 34 from 5 and 39 and 40 from 6.The diene reactivity of thiophene 13a in the gas phase was demonstrated by the formation of naphthalene from its reaction with benzyne generated from the thermolysis of indanetrione and by the formation of indene from 13a plus cyclopentadiene.Possible, but improbable, interpretations of the FVT results without invoking a five-membered hetaryne intermediate are considered.

Advances toward new antidepressants beyond SSRIs: 1-aryloxy-3-piperidinylpropan-2-ols with dual 5-HT1A receptor antagonism/SSRI activities. Part 2

Potent 5-HT1A/SSRIs at low nanomolar and subnanomolar concentrations were identified in a series of 1-(1H-indol-4-yloxy)-3-(4-benzo[b]thiophen-2-ylpiperidinyl)propan-2-ols.

Evolution of products in the combustion of scrap tires in a horizontal, laboratory scale reactor

A horizontal laboratory reactor was used to study the evolution of byproducts from the combustion of scrap tires at five nominal temperatures (ranging from 650 to 1050 C) and different oxygen:sample ratios A model was used to calculate the bulk air ratio (lambda), and the oxygen consumption was discussed considering this ratio lambda. More than 100 volatile and semivolatile compounds were identified and quantified by gas chromatography mass spectrometry, plotting their yields vs the bulk air ratio and temperature. Five different behaviors considering the bulk air ratio and the temperature were identified.

NMR Studies of Bond Orders in Heteroaromatic Systems

Fifty-seven for the ortho-benzylic coupling constant 4JMe-C=C-H (henceforth denoted as 4JOB) were obtained for a variety of heteroaromatic systems.It was shown that a good correlation exists between 4JOB when the methyl group is not alpha to the heteroatom and the SCF-MO bond order.This method can therefore be used as experimental means of determining bond orders in heteroaromatic systems.An examination of bond alternation in thirteen heteroaromatic systems has given a measure of relative “degree of aromaticity” for a larger number of systems than previously r eported by any single method.

Bacterial transformations of benzothiophene and methylbenzothiophenes

The abilities of three Pseudomonas strains to transform each of the six isomers of methylbenzothiophene was studied. These compounds would not support growth but were biotransformed in a cell suspension of one of the isolates and in cultures of the other two isolates while they grew on 1- methylnaphthalene or glucose. Sulfur-containing metabolites were identified by GC/MS and GC/FTIR, and when possible, by comparison with authentic standards. Sulfoxides and sulfones were frequently detected and were the most abundant products from 2- and 3-methylbenzothiophene. Two of the isolates oxidized the methyl groups to carboxylic acids which were abundant products from 3-, 5-, and 6-methylbenzothiophenes. Benzothiophenemethanols were often detected, but in very low amounts. 2,3-Diones were observed as metabolites of benzothiophene and those methylbenzothiophenes with a methyl group on the benzene ring. Isomers of tolyl methyl sulfoxide were observed as ring cleavage products from 6- and 7-methylbenzothiophene.
