alcohol 1 with ethyl vinyl ether in the presence of mercury (11) acetate followed by treatment with the same or a different alcohol in the presence of p-toluenesulfonic acid affords the symmetrical and unsymmetrical acetaldehyde acetals 3 in good overall yield. The method is easily scaled up and represents a significant improvement over currently available procedures.
摘要 在乙酸汞 (11) 存在下用乙基乙烯基醚处理伯醇 1,然后在对甲苯磺酸存在下用相同或不同的醇处理,初步形成乙烯基醚 2,得到对称和不对称乙醛缩醛 3 的总产率良好。该方法很容易扩大规模,并代表了对当前可用程序的显着改进。
