A new procedure for the protection of aldehydes and ketones as thioacetals promoted by catalytic amount of p-toluene-sulfonic acid and silica gel has been developed. This procedure offers versatility, short reaction time,excellent yield, good selectivity, and flexibility in terms of choice of solvent that can be utilized in this reaction. The procedure is easy to carry out and does not require aqueous
已经开发了一种通过催化量的对甲苯磺酸和硅胶促进作为硫缩醛保护醛和酮的新方法。该程序提供了多功能性、反应时间短、产率高、选择性好以及在选择可用于该反应的溶剂方面的灵活性。该程序易于执行,不需要水处理。在大多数情况下,简单的过滤然后去除溶剂会产生纯产品。
