一种新型植物生长调节剂4,6-二甲基-2-羧甲氧基嘧啶的合成

Synthesis of 4,6-Dimethyl-2-carboxymethoxy Pyrimidine

嘧啶及其衍生物具有良好生物活性,而芳氧乙酸类化合物对于植物的生长发育也具有较强的生物活性。以乙酰丙酮及尿素为主要原料合成4,6-二甲基-2-羟基嘧啶中间体,再与氯乙酸反应合成4,6-二甲基-2-羧甲氧基嘧啶。中间体和目标产物。产物结构经熔点(m.p.)、红外光谱(IR)、元素分析等手段得以确认。

Applied acetyl acetone and urea as the main raw material, 4,6-dimethyl-2-hydroxy pyrimidine intermediates was synthesized. Then the intermediates reacted with chloroacetic acid to synthesize 4,6-dimethyl-2-carboxy methoxy pyrimidine. The structures of intermediates and target product were characterized by melting point （m.p.）, infrared spectra （IR） and element analysis.
