  The one‐pot sequential coupling of benzylamines, boronic esters, and aryl iodides has been investigated. In the presence of an N‐activator, the boronate complex formed from an ortho‐lithiated benzylamine and a boronic ester undergoes stereospecific 1,2‐metalate rearrangement/anti‐SN2′ elimination to form a dearomatized tertiary boronic ester.

  The reaction of bicyclo[1.1.0]butyl pinacol boronic ester (BCB‐Bpin) with nucleophiles has been studied. Unlike BCBs bearing electron‐withdrawing groups, which react with nucleophiles at the β‐position, BCB‐Bpin reacts with a diverse set of heteroatom (O, S, N)‐centred nucleophiles exclusively at the α‐position. Aliphatic alcohols, phenols, carboxylic acids, thiols and sulfonamides were found to be

  研究了双环[1.1.0]丁基频哪醇硼酸酯（BCB-Bpin）与亲核试剂的反应。与带有吸电子基团的BCB在β位置与亲核试剂反应不同，BCB-Bpin仅与在α位置以杂原子（O，S，N）为中心的各种异核亲核反应。发现脂肪族醇，酚，羧酸，硫醇和磺酰胺是有效的亲核试剂，可轻松获得α-杂原子取代的环丁基硼酸酯。相反，位阻双磺酰胺和相关亲核试剂与BCB-Bpin在β'位置反应，生成具有高反选择性的环丙烷。讨论了选择性的起源。
