Hydrazide fixed to a resin represented by the following formula:
P-Q-CO-NH-NH2 (I)
where P represents a main chain of a resin polymer and Q represents a hydrocarbon side chain optionally having a substituent which may be boned via a heteroatom, and a hydrazone derived therefrom and fixed to a resin
P-Q-CO-NH-N=CH-R1 (II)
are provided, and solid phase synthesis of pyrazolone is conducted using the same, thereby enabling synthesis of pyrazolones by the application of the Mannich type reaction based on the solid phase synthesis and efficient construction of libraries for various kinds of them.
将酰肼固定在下式所代表的树脂上:
P-Q-CO-NH-NH2 (I)
其中,P 代表树脂聚合物的主链,Q 代表烃侧链,可选择具有可通过杂原子骨化的取代基,以及由此衍生并固定在树脂上的腙
p-q-co-nh-n=ch-r1 (ii)
提供了吡唑酮的固相合成方法,从而可以在固相合成的基础上应用曼尼希式反应合成吡唑酮,并有效地构建各种吡唑酮的化合物库。
