2-AMINO-3-FORMYLCHROMONE

2-Amino-3-formylchromone may be used in the preparation of the following:

• chiral Schiff base ligands (R)/(S)-2-amino-3-(((1-hydroxypropan-2-yl)imino)methyl)-4H-chromen-4-one
• hydrazone derivatives, required for the synthesis of heterocyclic Schiff′s bases having antimicrobial activity
• N-{4-[(6-chloro-4-oxo-4H-chromen-3-ylmethylene)amino]phenyl}-3,5-dimethyl-benzofuran-2-carboxamide
• N-{4-[(6-chloro-4-oxo-4H-chromen-3-ylmethylene)amino]phenyl}-1,4-dihydro-chromono [2,3-b]pyrrole-2-carboxamide
• 6-chloro-3-{[4-(2-thioxo-3,6-dihydro-2H-1,3,4-thiadiazin-5-ylamino)phenylimino] methyl}- 4-oxo-4H -chromene
• 3--(2-amino--4--oxo--4H--chromen--3--yl)methylidene)--6-- ethyl--2H--pyrano[3,2--c]quinolone--2,4,5(3H,6H)-trione

2-Amino-3-formylchromone (2-Amino-4-oxo-4H-1-benzopyran-3-carboxaldehyde) is a benzopyran derivative. It is a bicyclic heterocyclic molecule made up of a benzene ring fused to a heterocyclic pyran ring. It undergoes condensation with (R)-2-amino-2-phenylethanol to afford Schiff base ligand, which forms complexes with Cu(NO₃)₂ and Zn(NO₃)₂.
