CrO3/SiO2固载氧化剂对脱氢枞胺衍生物B环的氧化
Oxidation on ring B of dehydroabietylamine derivatives using CrO3/SiO2 solid-supported oxidizing reagent
摘要
Abstract
A supported oxidant CrO3/SiO2- was prepared by absorbing the CrO3 on silicon gel, and its oxidation characteristics was investigated for the oxidation of N-benzoyl-dehydroabietylamine to N-benzoyl-dehydroabietylamine-7-one in this paper. Effects of solvent types and quantities, reaction temperature, loading amount and oxidant dosage on the yield were examined. The test result indicated that N-benzoyl-dehydroabietylamine-7-one can be obtained with yield of 60 % by oxidation of 1 g (2. 57 mmol) N-benzoyl-dehydroabietylamine in the present of 2 equimolar amount of CrO3/SiO2 (loading amount 2 mmol/g) in 50 mL cyclohexane under the reflux temperature for 8 h. This reagent is easily prepared, it can be used in the field of allylic oxidation in relatively high oxidation selectivity, yields with simple procedure and easy purifications.关键词
