| Abstract: | Phthalic acid 1 has been converted to bis
(oxiran-2-ylmethyl) phthalate 2
followed by ring opening to di-tertiary amines viz: bis (3-[diethylamino)-2-hydroxypropyl] phthalate 3 and bis
[2-hydroxy-3-[piperidin-1-yl) propyl] phthalate 4. Conversion is carried through conventional as well as
non-conventional methods (microwave irradiation on solid support). Di-tertiary
amines 3 and 4 have been quaternized to give cyclic bis-quaternary ammonium
salts 3a-c and 4a,b which in turn are tested for their efficacy as plant growth
regulators on rice (Oryza sativa).
All the tested compounds are found to be good plant growth retardants. Compound
4c is found to be the best plant
growth retardant among the six newly synthesized compounds |
