Fifteen structurally different tertiary amineswith highly steric hindrance are obtained byalkylation of di-(methyl heptyl)-amine andsecondary alkyl primary amines with branched-chain alcohols,ethylene oxide and dodecenylchloride.These amine ligands with weakbasicity are used to extract rare elements andnoble...
build architecturally complex and functionally diverse tertiary alkylamines in a single step. This olefin-hydroaminoalkylation process involves a visible-light-mediated reduction of in-situ-generated iminium ions to selectively furnish previously inaccessible alkyl-substituted α-amino radicals, which subsequen...

Efficient synthesis of α-tertiary α-silylamines from aryl sulfonylimidates via one-pot, sequential C-Si/C-C bond formationsAn efficient and flexible route for the synthesis of α-tertiary (α,α-dibranched) α-silylamines via ... Han, X.-J.,Yao, M.,Lu, C.-D. - 《Organic Letters...
The ubiquity of tertiary alkylamines in pharmaceutical and agrochemical agents, natural products and small-molecule biological probes1,2 has stimulated efforts towards their streamlined synthesis3–9. Arguably the most robust method for the synthesis of
Reliable N-alkylations of secondary amines have been developed. By using DIAD and TPP (or PS-TPP) a variety of secondary amines can be converted to the corresponding tertiary amines in good to excellent yields with diverse alkylhalides; no formation of quaternary amine salts are observed. These...
Secondary and tertiary amines are selectively prepared in high yields by a one-pot reduction / multiple alkylation procedure from aromatic nitro compounds with styrenes, cyclic olefins or heterofunctionalised olefins, carbon monoxide and hydrogen in the presence of [Rh(cod)Cl]2 as catalyst.关键词:...

Chiral tertiary alcohols are an important structural motif, but the general methodologies for the synthesis are less reported. Herein, the authors report a Ni(ІІ)-catalyzed asymmetric alkenylation and arylation of aryl ketones with organoborons under air via a 1,5-metalate shift to obtain ch...
