by rat liver preparations is shown in Scheme 1, and is similar to that proposed by Jerina et al. (1968) for the metabolism of naphthalene. In both cases the action of the epoxide hydratase leads to the production of the trans-diol only. The occurrence of ris-indane-f,2-diol in addition to the trans-diol as a metabolite of indene in the rat (Brooks &Young, 1956) could be explained by the metabol...

A method capable of determining 13 PAHs (acenaphthene, anthracene, benzo[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, chrysene, dibenzo[ah]anthracene, fluoranthene, fluorene, indene[1,2,3-cd]pyrene, phenanthrene and pyrene) in a mixture of 16 EPA PAHs by second derivative synchronous spectrofluorometry in the constant wavelength mode was developed. It has not been p...

In the title compound, C(27)H(20)ClNO(3), the two cyclo-pentane rings adopt envelope conformations. The pyrrolidine ring also adopts an envelope conformation (with the spiro C atom as the flap) and its least-squares plane (fitted to five atoms) makes dihedral angles of 66.50 (9), 77.36 (8) and 73.76 (8)° with the chloro-benzene ring and the two 2,3-dihydro-1H-indene ring systems, respectively. ...

The title compound, C(16)H(10)N(2)O(5)S, was synthesized via the condesation of dihydro-thio-phen-3(2H)-one 1,1-dioxide, 1H-indene-1,2,3-trione and malononitrile in ethanol. The 2,3-dihydro-thio-phene 1,1-dioxide and pyran rings adopt envelope conformations. The mean planes through the planar part of the pyran ring and the benzene ring are nearly perpendicular, forming a dihedral angle of 88.40...

Photoinduced cyclization of o-alkenylaryl isocyanides with (PhS)2 in the presence of (PhTe)2 affords the corresponding bisthiolated indene derivatives in good yields via radical cyclization process by thio radical. The procedure can be applied to the construction of tetracyclic systems by using bis(o-aminophenyl) disulfides in place of (PhS)2. In sharp contrast, when o-alkynylaryl isocyanides a...

products and tryptic digestion and ‘mapping’ of the peptides (Sargent & Vadlamudi, 1968; Mainwaring, 1964), indicated that globin was a product of the wheat-germ system. This globin was shown to be a mixture of the embryonic P and E globins by use of [3H]globin markers in the peptide ‘mapping’. It appears from our findings that a t 12h of incubation in uitro the mRNA for globin is present, but ...

Non-Scientific Abstract Throughout the past decade, AIDS has become one of the most threatening and prevalent diseases in America. As the number of patients suffering from the potentially fatal disease increases, so does the demand for different types of drug therapy. One of the more successful therapies is Crixivan, a drug produced by MERCK. Although highly effective at slowing the spread of ...

The first chapter focuses on the introduction of iodine m ediated carbocyclisations and their applications continue to present a stim ulating challenge in targetand diversityoriented syntheses. Literature overview of m ore than past two decades about this area of research has been highlighted by including key examples along with the ir m echanistic aspects. The second chapter discusses applicat...
