Six derivatives of 2-aminoindane-2-phosphonic acid and 1-aminobenzylphosphonic acid were synthesized. The compounds were tested both as inhibitors of buckwheat phenylalanine ammonia-lyase (in vitro) and as inhibitors of anthocyanin biosynthesis (in vivo). (±)-2-Amino-4-bromoindane-2-phosphonic acid was found to be the strongest inhibitor from investigated compounds. The results obtained are a basis for design of phenylalanine ammonia-lyase inhibitors useful in the enzyme structure studies in photo labelling experiments.

(Chemical Equation Presented) Substituted 1,3-dihydro-2H-isoindoles (2, isoindolines) were prepared and subjected to palladium-catalyzed formate reduction. Alkyl isoindolines were reduced to 4,5,6,7-tetrahydro-2H-isoindoles (1). Only partial reduction was observed for 5-methoxyisoindoline, and 4-methoxy-, 5-carbomethoxy-, amino-, and amidoisoindolines were inert to the reaction. Halogen-substituted isoindolines were dehalogenated and reduced to 4,5,6,7-tetrahydro-2H-isoindoles. Isoindole 24 was also reduced to a mixture of an isoindoline and a 4,5,6,7-tetrahydro-2H-isoindole. In contrast, 2,3-dihydro-1H-indoles 21 underwent dehydrogenation to give thermodynamically stable indoles. Theoretical calculations show the significant difference in aromaticity between isoindoles and indoles, corresponding to the observed differences in reactivities. Tetrahydro-2H-isoindoles 1 were oxidized to 4,5,6,7-tetrahydroisoindole-1,3-diones in the presence of NBS and air.
Electro-organic reactions. Part 41. Diels-Alder reaction of o-quinodimethanes from the cathodic reduction of α,α'-dibromo-1,2-dialkylbenzenes

Cathodic reduction of α,α'-dibromo-1,2-dialkylbenzenes in DMF containing ET4N+ Br- as supporting electrolyte, in the presence of dienophiles (e.g. maleic anhydride derivatives), yielded Diels-Alder adducts of o-quinodimethanes. Selective reduction of the benzylic dibromides was often possible even when their irreversible cyclic voltammetric reduction peak potentials were more negative than the E(o) values for the anhydrides. This might be a consequence of redox catalysis, with the anhydrides having a dual role as mediators and dienophiles.

Low-pressure thermal generation of a range of o-alkylthiophenylcarbenes produces, in addition to the normal insertion products, styrenes and 1,3-dihydrobenzothiophenes-clearly arising from rearrangement.The main features of their mechanism of formation are established by deuterium-labelling studies: in both cases participation by S-ylids implicated.
