《有机化学基础》是中学化学的重要组成部分,也是历年高考必考内容之一。从近几年各地区高考化学试题来看,考查题型均为选择题和有机推断合成综合题,在选择题和综合题的命题中,都会或多或少提供一些新信息,其中药物或药物中间体合成化学为有机合成与推断开辟了广泛的题源。例如,2009年江苏卷中治疗高血压的药物——多沙唑嗪盐酸盐的合成,2010年安徽理综卷中医药中间体抗凝血药的合成,2013年上海卷中祛痰药沐舒坦的合成等等。这类题的特点是新颖,虽然一些药物的结构往往较为复杂,但仔细剖析,发现问题的落点还是较低 “Organic Chemistry Fundamentals” is an important part of chemistry in secondary schools, but also one of the examinations over the years the college entrance examination. In recent years, the regional college entrance examination chemistry test point of view, test questions are multiple choice and organic inference synthesis synthesis questions, multiple choice questions and comprehensive questions in the proposition, will be more or less to provide some new information, including drugs or drugs Intermediate synthetic chemistry opens up a wide variety of sources for organic synthesis and inference. For example, Jiangsu volume in 2009 the treatment of hypertension drug - doxazosin hydrochloride synthesis, Anhui Science Volume synthesis of Chinese medicine in 2010 the synthesis of anticoagulant drugs, Shanghai volume in 2013 expectorant medicine Mu Comfortable synthesis and so on. The characteristics of such questions are novel. Although the structure of some drugs is often complicated, careful analysis reveals that the problem is still relatively low
