日期:——
protonation/deuteration and reduction of in situ-formed enamines in the presence of water and pinacolborane was developed. Regioselective β-deuteration of tertiary amines was achieved with high chemo- and regioselectivity. D2O was used as a readily available and cheap source of deuterium. Mechanisticstudies indicated that B(C6F5)3 could activate water to promote the protonation and reduction of enamines.
开发了一种高效的B(C 6 F 5)3催化串联质子化/氘代和在水和频哪醇硼烷存在下还原原位形成的烯胺的方法。叔胺的区域选择性β-氘化具有高的化学和区域选择性。D 2 O被用作一种容易获得且廉价的氘源。机理研究表明,B(C 6 F 5)3可以活化水以促进烯胺的质子化和还原。

protocol for the direct reductive amination of aldehydebisulfite adducts is reported. Bisulfite adducts of aliphatic and aromatic aldehydes, on treatment with an organic base under non-aqueous conditions liberate the aldehyde in situ, which then undergoes efficient reductive amination with amines in the presence of sodium triacetoxyborohydride. Bisulfite adducts - reductive amination - sodium triacetoxyborohydride

reaction to include amine nucleophiles to form C–N bonds through the utilization of N-heterocyclic phosphine-butane (NHP-butane) has been developed. Both aliphatic alcohols and benzyl alcohols are suitable substrates for C–N bond construction. Various acidic nucleophiles such as benzoic acids, phenols, thiophenol, and secondary sulfonamide also provide the desired products of esters, ethers, thioether
