6-tetrame-thylpiperidide (LTMP) and underwent methylation or nucleophilic addition with aldehydes and ketones. The successive dehydration of the allylic alcohols with trimethylsilyl trifluoromethanesulfonate (TMSOTf) gave α-phenyltellanyl α,β-unsaturated aldehydes, which transformed to some useful compounds.
摘要 苯乙氧基乙醛二乙缩醛与2,2,6,6-四甲基哌啶(LTMP)锂原位成功制备β-乙氧基-α-苯基乙炔基乙烯基锂,并与醛和酮进行甲基化或亲核加成。烯丙醇与三氟甲磺酸三甲基甲硅烷基酯 (TMSOTf) 的连续脱水得到 α-苯基四氢萘基 α,β-不饱和醛,其转化为一些有用的化合物。
