- Isosteres of ester derived glucose uptake inhibitors
-
Glucose transporters (GLUTs) facilitate glucose uptake and are overexpressed in most cancer cells. Inhibition of glucose transport has been shown to be an effective method to slow the growth of cancer cells both in vitro and in vivo. We have previously reported on the anticancer activity of an ester derived glucose uptake inhibitor. Due to the hydrolytic instability of the ester linkage we have prepared a series of isosteres of the ester moiety. Of all of the isosteres prepared, the amine linkage showed the most promise. Several additional analogues of the amine-linked compounds were also prepared to improve the overall activity.

- Flash vacuum pyrolysis over magnesium. Part 1 - Pyrolysis of benzylic, other aryl/alkyl and aliphatic halides
-
Flash vacuum pyrolysis over a bed of freshly sublimed magnesium on glass wool results in efficient coupling of benzyl halides to give the corresponding bibenzyls. Where an ortho halogen substituent is present further dehalogenation gives some dihydroanthracene and anthracene. Efficient coupling is also observed for halomethylnaphthalenes and halodiphenylmethanes while chlorotriphenylmethane gives 4,4′-bis(diphenylmethyl)biphenyl. By using α,α′-dihalo-o-xylenes, benzocyclobutenes are obtained in good yield, while the isomeric α,α′-dihalo-p-xylenes give a range of high thermal stability polymers by polymerisation of the initially formed p-xylylenes. Other haloalkylbenzenes undergo largely dehydrohalogenation where this is possible, in some cases resulting in cyclisation. Deoxygenation is also observed with haloalkyl phenyl ketones to give phenylalkynes as well as other products. With simple alkyl halides there is efficient elimination of HCl or HBr to give alkenes. For aliphatic dihalides this also occurs to give dienes but there is also cyclisation to give cycloalkanes and dehalogenation with hydrogen atom transfer to give alkenes in some cases. For 5-bromopent-1-ene the products are those expected from a radical pathway but for 6-bromohex-1-ene they are clearly not. For 2,2-dichloropropane and 1,1-dichloropropane elimination of HCl occurs but for 1,1-dichlorobutane, -pentane and -hexane partial hydrolysis followed by elimination of HCl gives E, E-, E,Z- and Z,Z- isomers of the dialk-1-enyl ethers and fully assigned 13C NMR data are presented for these. With 6-chlorohex-1-yne and 7-chlorohept-1-yne there is cyclisation to give methylenecycloalkanes and -cycloalkynes. The behaviour of 1,2-dibromocyclohexane and 1,2-dichlorocyclooctane under these conditions is also examined. Various pieces of evidence are presented that suggest that these processes do not involve generation of free gas-phase radicals but rather surface-adsorbed organometallic species.

- Novel Substituted Poly(benzothiophenes); Controlling the n- and p-Doping Potentials

Methyl-, chloro- and fluoro-substitution in the C6 ring has little effect on the oxidation of polybenzothiophene films to the p-doped conducting form, but has a marked effect on reduction to the n-doped form; poly(5,6-dichlorobenzothiophene) is n-do

- Synthesis of Fluorinated Derivatives of Benzofluoranthene and Indenopyrene and 8,9-dihydro-8,9-epoxybenzofluoranthene
-
The synthesis of several select fluorinated derivatives of benzofluoranthene and indenopyrene is described.In the benzofluoranthene series, the 8- and 9-fluoro derivatives have been prepared by Wittig reaction of the 1,2-bis salt of the appropriate fluorobenzene with acenaphthenequinone under phase-transfer conditions.The synthesis of 2-fluoroindenopyrene was achieved by photocyclization of 1-(β,β-difluorovinyl)benzofluoranthene followed by dehydrofluorination in methanolic sodium methoxide.This represents a new method for the construction of the indenopyrene skeleton. 8,9-Difluoroindenopyrene was prepared from 1-(2-amino-4,5-diflurophenyl)pyrene by diazotization followed by coupling in the presence of copper-bronze.In addition to these fluorinated derivatives, the synthesis of 8,9-dihydro-8,9-epoxybenzofluoranthene, a suspect ultimate tumorigenic metabolite of benzofluoranthene, is reported.This arene oxide was prepared from the trans-8,9-bromo acetate by benzylic bromination and subsequent treatment with sodium methoxide in anhydrous THF.
