通过将酰胺与苯乙烯进行钴催化的烯丙基化反应,已经开发了一种有效的特权烯丙基胺的合成方法,其中DMSO既用作溶剂,又用作α-亚甲基源。该转化具有高收率和对线性产物的(E)-异构体的选择性。通过实验和计算研究,还推导了顺序的K 2 S 2 O 8介导的氧化偶联/钴辅助的区域选择性烯烃插入/β-H消除/烯烃解离/氢化物转移过程。

The present invention relates to the field of pharmaceutical technology and describes a novel advantageous preparation for an active ingredient. The novel preparation is suitable for producing a large number of pharmaceutical dosage forms. In the new preparation an active ingredient is present essentially uniformly dispersed in an excipient matrix composed of one or more excipients selected from the group of fatty alcohol, triglyceride, partial glyceride and fatty acid ester.
Targetable diagnostic and/or therapeutically active agents, e.g. ultrasound contrast agents, comprising a suspension in an aqueous carrier liquid of a reporter comprising gas-containing or gas-generating material, said agent being capable of forming at least two types of binding pairs with a target.
