标题:一种2,6-二氯醌-4-氯亚胺的绿色高效制备方法
摘要:2,6‑二氯醌‑4‑氯亚胺是一种非常重要的医药化工中间体,其经济价值较高,市场需求量巨大,但是迄今尚无相关专利或论文报道它的合成路线.本专利创造性地提出一种绿色高效的化学合成方法.我们以10%稀盐酸用作溶剂,含活性氯6~14%的次氯酸钠溶液为氧化剂和氯代试剂,2,6‑二氯‑4‑氨基苯酚为起始原料.然后,利用恒压滴液漏斗将原料的盐酸溶液缓慢滴加到冰浴下的次氯酸钠溶液中进行反应,便可高收率和高选择性地获得目标产物2,6‑二氯醌‑4‑氯亚胺.

摘要:The present invention is related to cis-diols and biological methods of producing cis-diols. The present invention further relates to processes for subsequently converting such silane cis-diols to the more stable acetonide derivatives, as well as a process for converting silane cis-diols to the corresponding catechols and the compounds produced thereby. The present invention also provides chemical methods for the conversion of said silane cis-diols and acetonide compounds to epoxy, saturated and otherwise modified derivatives. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that is will not be used to interpret or limit the scope or meaning of the claims.
