一般說明

二水氯化钙是一种无机化合物,通常在有机合成中用作环保型催化剂。它也用于不对称转化反应。

應用

二水氯化钙可作为催化剂用于:      
  • 箱式配体环境下的不对称 1,4 加成和 [3+2]-环加成反应。      
  • 通过乙基/乙酸甲酯、苯胺和甲醛的一锅三组分缩合反应合成六氢嘧啶衍生物。

它也可以作为钙前体,以磷酸(H3PO4)和聚丙烯酸(PAA)为原料,通过溶胶-凝胶法合成大孔/中孔磷酸二钙单体(CaHPO4)。

At present, typical approaches employed to repair fractures and other bone lesions tend to use matrix grafts to promote tissue regeneration. These grafts act as templates, which promote cellular adhesion, growth and proliferation, osteoconduction, and even osteoinduction, which commonly results
