1 Claisen, R. L.; Lowman, O. Ber. 1887, 20, 651. Rainer Ludwig Claisen (1851-1930), born in Cologne, Germany, probably had the best pedigree in the history of organic chemistry. He apprenticed under Kekulé, Wöhler, von Baeyer, and Fischer before embarking on his own independent research.  Rainer Ludwig Claisen (1851-1930)生于德国科隆,他在有机化学史上可谓师出名门。在他独立进行研究之前曾经师从凯库勒,维勒,von Baeyer和Fischer 。
