Synthesis of novel dibenzo-2,6,9-triazabicyclo[3.3.1]nonanes from o-tosylamino- and o-mesylaminobenzaldehydes

“…3,4 13 (3 Carboxypropyl) 6,12 epimino 5,11 ditosyl 5,6,11,12 tetrahydrodibenzo[b, f ] 1,5 diazocine (3a). A mixture of alde hyde 1 (1.37 g, 5 mmol) and γ aminobutyric acid (2a) (0.50 g, 5 mmol) in 10 mL of PrOH was refluxed for 5 h and cooled.…”

The novel azomethine ligands for binuclear copper(II) complexes with ferro- and antiferromagnetic properties

“…The Schiff bases 5a-c, e were prepared by coupling 2-tosylaminobenzaldehyde (9: X ¼ NTs) [34,35] or 2-hydroxybenzaldehyde (9: X ¼ OH) with 2-alkylamino-5-nitroaniline 10 [36] in toluene (Scheme 1).…”

Novel N-benzimidazolyl-2-thione o-tosylamino(hydroxy)azomethinic tautomeric ligand systems and their metallochelates

“…The synthesis of type 1 compounds has been carried out following the transformations 10,11 described in Scheme 1. …”
