The system chlorine dioxide–dimethylformamide in combination with or without a catalytic amount of MoCl5, CeCl3, ZrOCl2, or VO(acac)2 induces oxidative chlorination of a number of bicyclic terpene alcohols and vicinal diols. 2α-Chloropinan-3-one, 3α-chloro-10β-pinan-4-one, 5α-chloro-3α-hydroxycaran-4-one, 5β-chloro-3β-hydroxycaran-4-one, and 4α-chloro-2α-hydroxypinan-3-one were thus synthesized in
二氧化氯-二甲基甲酰胺体系与有或没有催化量的MoCl 5,CeCl 3,ZrOCl 2或VO(acac)2组合使用,会引起许多双环萜烯醇和邻二醇的氧化氯化反应。2α-氯丁酮3-one,3α-氯10β-pinan-4-one,5α-氯3α-hydroxycaran-4-one,5β-氯-3β-hydroxycaran-4-one和4α-chloro-2α因此以良好的制备产率合成了-羟基pinan-3-one。
