  开发了一种连续流法来合成溴甲基三氟硼酸钾，这是铃木-宫浦偶联剂的关键前体。连续流法用于生产从克到千克的规模的溴甲基三氟硼酸钾，成功的过程利用了分批合成所需资源的一小部分。在该工厂中，一个由三个人组成的小组在不到4周的时间内生产了约100千克溴甲基三氟硼酸钾。此过程使得使用溴代甲基三氟硼酸钾及其衍生物进行多千克级的Suzuki-Miyaura偶联既实用又经济。

  A full account of the development of the first catalytic manifold for the additions of allylboronates to aldehydes is described. The thermal additions (both diastereospecific and enantioselective) of 2-carboxyester 3,3-disubstituted allylboronates 1 to both aromatic and aliphatic aldehydes give biologically and synthetically important exo-methylene butyrolactones 2 containing a β-quaternary carbon

  日期：2019.11.18

  on the boron atom, thus stabilizing or not stabilizing the corresponding adjacent radical, it is possible to control the behavior of α-boronyl xanthates and construct a large variety of terminal or internal boronates in a modular fashion. The remarkable tolerance of polar groups and the ability to introduce quaternary centers are particularly noteworthy features of this process.

  与硼被sp3-杂化的二乙醇胺基硼酸酯[B（DEA）]相比，硼上具有空p轨道的品纳可乐硼酸酯（Bpin）可以稳定相邻的碳原子团。通过将频哪醇或二乙醇胺部分交替地放置在硼原子上，从而稳定或不稳定相应的相邻基团，可以控制α-硼基黄原酸酯的行为，并以模块化的方式构建多种末端或内部的硼酸酯。极性基团的显着耐受性和引入四元中心的能力在此过程中特别值得注意。

  (Azidomethyl)boronic esters of 1,2-dicyclohexyl-1,2-ethanediol (“DICHED”) and pinanediol have been prepared from the corresponding (bromomethyl)boronic esters. Conversion to (2-azido-1-chloro- or bromoethyl)boronic esters by reaction with a (dihalomethyl)lithium followed. Attempted displacement of halide from DICHED (2-azido-1-haloethyl)boronates with alkoxides failed. Reaction of either pinanediol

  由相应的（溴甲基）硼酸酯已经制备了1，2-二环己基-1，2-乙二醇（“叠氮基”）硼酸酯（“ DICHED”）和pin烷二醇。然后通过与（二卤甲基）锂反应转化为（2-叠氮基-1-氯-或溴乙基）硼酸酯。尝试用醇盐从DICHED（2-叠氮基-1-卤代乙基）硼酸酯中取代卤化物失败。pin烷二醇或DICHED（2-叠氮基-1-氯甲基）硼酸酯与乙酸钠在乙酸中的反应生成1-乙酰氧基衍生物，为约1：1的非对映异构体混合物，表明α-硼烷基碳正离子中间体可能参与其中。在氯化氢在二恶烷溶液中的铂上的pin烷二醇叠氮基硼酸酯在铂上的氢化伴随脱乙酰基化反应，形成不纯的（2-氨基-1-羟乙基）硼酸酯盐酸盐。尝试纯化该物质导致脱硼为乙醇胺。乙酰化得到pin二醇（2-乙酰氨基-1-乙酰氧基乙基）硼酸酯。
