Deuteration of several lignanolactones, using 2H3PO4·BF3/2H2O as the deuteration reagent, is described, affording new stable isotopically pure polydeuterated lignans. All aromatic hydrogens are exchanged, including the less active ones. The order of 1H/2H exchange is studied by comparing calculated electrostatic potential values and experimental observations. Labile deuteriums are exchanged back to hydrogens with methanolic HCl to achieve stable isotopically pure compounds. Copyright © 2008 John Wiley & Sons, Ltd.
本文介绍了使用 2H3PO4-BF3/2H2O 作为氘化试剂对几种木质素内酯进行氘化,从而得到了新的稳定的同位素纯多氘化木质素。所有的芳香族氢都被交换了,包括活性较低的氢。通过比较计算的静电位值和实验观察结果,研究了 1H/2H 交换的顺序。用甲醇盐酸将不稳定的氘交换回氢,从而获得稳定的同位素纯化合物。Copyright © 2008 John Wiley & Sons, Ltd. All Rights Reserved.
