expeditive construction of various polyfunctionalized 5‐, 6‐, and 7‐membered heterocycles, such as furans, pyrroles, quinolines, benzo[b]thieno‐[2,3‐b]pyridine, naphthyridines, fused pyrazoles, and 2,3‐dihydro‐benzo[c]azepines. The latent silyl group has been converted into various carbon–carbon bonds in most heterocycle types.
已经制备了新的Li,Mg和Zn的β-甲硅烷基化有机金属试剂,并将其用于快速构建各种多官能化的5、6和7元杂环,例如呋喃,吡咯,喹啉,苯并[ b ]噻吩并[2,3- b ]吡啶,萘啶,稠合吡唑和2,3-二氢-苯并[ c ]氮杂s。在大多数杂环类型中,潜在的甲硅烷基已转化为各种碳-碳键。
