Superelectrophilic sp3 C–H carbonylation of n-octyl acetate as a way to new bifunctional neo-octanes
摘要:
Carbonylation of n-octyl acetate in the presence of CBr4 center dot 2AlBr(3) followed by treatment with nucleophiles such as alcohols, amines or (het)arenes affords 7-acetoxy-2,2-dimethylheptanoyl-containing products.
Superelectrophilic sp 3 C H bond intermolecular functionalization of primary alcohols C n H 2 n +1 OH ( n = 7, 8, 9) leading to new neo-alcohols with remote functional groups or new macrocyclic lactides

Two new types of Csp3–H functionalization reactions of alcohols CnH2n+1OH (n = 7–9) with the superelectrophilic complex CBr4·2AlBr3 and CO have been developed. In the presence of various nucleophiles (EtOH, iPrOH, CF3CH2OH, HCF2CF2CH2OH, furan, pyrrole, thiophene, morpholine, and anisole), the reaction furnishes new neo-alcohols with remote functionalgroups. In the absence of external nucleophiles
已经开发了两种新型的醇C n H 2 n +1 OH(n = 7–9)与超亲电子配合物CBr 4 ·2AlBr 3和CO的C sp 3 -H官能化反应。在各种亲核试剂(EtOH,i PrOH,CF 3 CH 2 OH,HCF 2 CF 2 CH 2 OH,呋喃,吡咯,噻吩,吗啉和苯甲醚)的存在下,该反应提供了具有远程官能团的新醇。在没有外部亲核试剂的情况下,产生了大环丙交酯。
