Ethyl acetoacetate, methyl acetoacetate, dimethyl acetoacetamide, monomethyl aceto-acetamide, and acetoacetanilide are low-color copromoters for room-temperature cure of unsaturated polyesters.
Elaborating on the procedure of the research, Shaneghi reiterated, "First, we mixed ethanol and
ethyl acetoacetate together at the room temperature.
W e synthesized 5,6-dehydrokawain (1) and yangonin (4) via three steps from the dianion of ethyl acetoacetate achieving a good yield and determined their conformations by high resolution NMR and x-ray crystallographic analysis.
00 g) in dry THF (30 ml) was added dropwise for 10 min to the dianion of ethyl acetoacetate (2.
Several dilithiated beta-ketoesters, such as
ethyl acetoacetate, and beta-diketones, such as 1-benzoylacetone, were condensed with polylithiated methyl 2-(aminoulfonyl)-benzoate to give C-acylated intermediates that were not isolated but cyclized directly to the 3-substiuted 1,2-benzisothiazole 1,1-dioxides.
