of enantiopure 4‐oxy‐substituted 3‐aminopyrrolidines arising from the enantioselective ring‐opening of meso‐3‐pyrroline oxide have been developed as catalysts for the asymmetric, anti‐selective Mannichreaction (see scheme; PMP=p‐methoxyphenyl; PG=protecting group). Very high catalytic activity (down to 0.01 mol % loading) and stereoselectivity have been recorded.

bioactive compounds. However, the atropisomerism arising from a restricted rotation around an N–N bond is largely overlooked. Here, we describe a method to access the first enantioselective synthesis of N–N biaryl atropisomers via a Cu-bisoxazoline-catalyzed Friedel–Crafts alkylation reaction. A wide range of axially chiral N–N bisazaheterocycle compounds were efficiently prepared in high yields with

hydroazidation of unactivated alkenes using ABX2014;N3 as an initiator has been developed at room temperature, wherein hydrogen azide (HN3) acts as both hydrogen and azidating agent. Notably, the HN3 reagent was generated from azidotrimethylsilane (TMSN3) and acetic acid in situ. The reaction itself displays broad substrate scope, good yields and excellent regioselectivities.
在室温下开发了使用ABX2014; N 3作为引发剂的未活化烯烃的反马尔科夫尼科夫加氢叠氮反应,其中叠氮化氢(HN 3)同时充当氢和叠氮化剂。值得注意的是,HN 3试剂是由叠氮基三甲基硅烷(TMSN 3)和乙酸原位生成的。该反应本身显示出宽的底物范围,良好的产率和优异的区域选择性。
