- W4383894804 abstract "ABSTRACT 7-Hydroxy-4-methyl coumarin(H1) compound have been synthesized by resorcinol and ethyl acetoacetate reaction. 4-methyl-2-oxo-2H-chromen-7-yl 2-chloroacetate(H2) is highly reactive compounds. It has been used as intermediate in some reactions. It has been synthesized and reacted with hydrazine hydrate to produce4-methyl-2-oxo-2H-chromen-7-yl 2-hydrazinylacetate (H3).Schiff Bases Compound (H4) is synthesized by reacting the compound (H3) with P-hydroxy benzaldehyde, then reacted(H4) with sodium azide, mercaptoacetic acid, chloroacetyl chloride and anhydrides such as (3- nitro phathalic anhydride, maleic anhydride, succinic anhydride) which produced tetrazole(H5), thiazolidinone (H6), β–Lactam (H7), and Oxazepine Compounds(H8-H10) respectively. The prepared derivatives have been identified by FT-IR, 1HNMR. Some of these compounds have bene screened for their antioxidant activity." @default.
