Assessment of the regioselectivity in the condensation reaction of unsymmetrical o-phthaldialdehydes with alanine

, p. 224 - 239 (2017/12/08)
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.

Synthesis, photochemistry and photorelease properties of 7-methoxy-3-nitro-2-naphthalenemethanol (MNNM) are described. Photoirradiation (≥370 nm) of MNNM covalently linked to hippuric acid causes efficient release (~90%) of hippuric acid.

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.

THE SELECTIVE BENZYLIC BROMINATION OF o-XYLENES. A USEFUL SYNTHESIS OF PHTHALIDES
Box, Vernon, G. S.,Yiannikouros, George P.
, p. 1261 - 1270 (2007/10/02)
The free radical bromination of aryl methyl groups can be controlled by the strategic positioning of a remote stereo-electronic blocking group on the aryl ring.This tactic leads to the efficient synthesis of selectively benzylically brominated molecules which are useful synthetic intermediates.This methodology has been applied to the synthesis of some phthalides.
