Synthesis of N-{2-[1-(prop-2-yn-1-yloxy)ethoxy]ethyl}-cytisinecarbothioamide and steric structure of its hydrolysis product, N-(2-hydroxyethyl)cytisinecarbothioamide
摘要:
The reaction of 2-[1-(prop-2-yn-1-yloxy)ethoxy]ethyl isothiocyanate with alkaloid cytisine gave the corresponding thiourea derivative which was subjected to partial hydrolysis on heating in boiling aqueous ethanol or complete hydrolysis in the presence of a catalytic amount of an acid. The structure of the hydrolysis product, N-(2-hydroxyethyl)cytisinecarbothioamide, was proved by X-ray analysis.
