在电子信息储存的年代里,可以用数字具体地表明在过去几年中有机合成的动向。1972年化学文摘中摘录的有关合成和全合成的工作占2.65％,而1982年占2.97％左右。1972年,论文题目中关于立体选择性、对映选择性、非对映选择性、手征性和不对称合成工作仅占0.12％,而1982年已占0.27％。有关立体和对映专一性反应的工作百分率,在最近十年中成倍增长,由于这个原因,在1982年发表了一系列复杂天然产物的合成工作是不足为奇的。然而,在这里首先提及以下的工作: 新的合成方法和试剂 1982年,Danishefsky等[J.Am.Chem.Soc.,1982,104,358,6457,6459]报道了由氯化锌或三氟化硼催化
In the era of electronic information storage, numbers can be used to indicate the trends of organic synthesis in the past few years. The total number of syntheses and total syntheses extracted from the Chemical Abstracts in 1972 was 2.65%, compared with 2.97% in 1982. In 1972, the papers on stereoselective, enantioselective, diastereoselective, chiral and asymmetric synthesis accounted for only 0.12%, while in 1982 accounted for 0.27%. The percentage of work on stereospecific and enantiospecific responses has multiplied in the last decade, for which reason it is not surprising that a series of complex synthetic natural products were published in 1982. However, the following work is first mentioned here: New Synthesis Methods and Reagents In 1982, Danishefsky et al [J.Am.Chem.Soc., 1982,104,358,6457,6459] reported that zinc chloride or trifluoro Boron catalysis
