Indole as a dienophile in inverse electron demand Diels-Alder reactions. 3. Intramolecular reactions with 1,2,4-triazines to access the canthine skeleton
摘要:
The intramolecular inverse electron demand cycloaddition of indole with 1,2,4-triazines connected by a tri- or tetramethylene tether linking the indole N-1 position with the triazinyl 3-position successfully produces the canthine skeleton and the homologous system with a seven-membered D-ring.

AS THE RESISTANCE of Staphylococcus aureus to antibiotics represents a major threat to global health, anti-infectives with novel mechanisms must be developed. Novel compounds were generated as potential phenylalanine tRNA synthetase (PheRS) inhibitors based on the published homology model of S. aureus PheRS to aid the design process using Molecular Operating Environment (MOE) software. PheRS was selected as it is structurally unique enzyme among the aminoacyl-tRNA synthetases (aaRS), it is considerably different from human cytosolic and human mitochondrial aaRS and it is essential and conserved across bacterial species. The designed compounds were synthesized according to different clear schemes. The compounds were confirmed by H-1 NMR, C-13 NMR, HRMS and/or microanalysis, and they were microbiologically evaluated.
