One approach for the synthesis of isoindolinones, a privileged bioactive heterocyclic core structure, involves a condensation reaction of o-phthaldialdehydes with a suitable nitrogen-containing nucleophile. This fascinating reaction is revisited here in the context of the use of o-phthaldialdehydes that contain additional substituents in the aromatic ring leading to a detailed analysis of the regioselectivity of the reaction. Eleven monosubstituted o-phthaldialdehydes were synthesised and reacted with alanine. The regioselectivity observed across the eleven substrates led to the design of a disubstituted substrate that reacted with very high control. A gram-scale reaction followed by esterification gave one major regioisomer in high yield. In addition, the regioselectivity observed on reaction of two novel monodeuterated substrates led to an increased mechanistic understanding.

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.
