细胞分裂素6─BA合成新方法的研究
The Study on the New Synthetic Method of Cytokinin-6-Benzylaminopurine(6-BA)
Abstract
用医药工业的副产物乙酰基次黄嘌呤（Ⅰ）在弱酸条件下水解，生成次黄嘌呤（Ⅱ），经三氟氧磷在吡啶溶液中缩合，生成6-吡啶盐中间体（Ⅲ），再与苄胺反应，制得高效植物细胞分裂素6-bA（Ⅳ）。 Hypoxanthine(Ⅱ) was reacted with POCl3 in pyridine to give 6-pyridinyl purine salt(Ⅲ) , which was condensed with benzylamine to give cytokinin-6-benzylaminopurine(Ⅳ) in good yields.The chemical structure of I was established by elemental analysis, IR and H1NMR.I was an important plant growth regulator.
