Treatment of N-phenyl- a well as N-methyl-3-(tri-bar|n-butylstannyl)-propionamide with 2 equiv of bar|n-butyllithium in the presence of 1,4-diazabicyclo[2.2.2]octane at −78°C in tetrahydrofuran produced the corresponding dilithio derivatives (homoenolate dianions) 4 and 8 respectively. Reaction with various electrophiles (1 equiv) gave the terminally substituted amides in good yields.
N-苯基-一个以及N-甲基-3-治疗(三-巴| N -butylstannyl) -丙酰胺与2当量的巴| N丁基锂在1,4-二氮杂双环的存在[2.2.2]辛烷在-78℃下,在四氢呋喃中分别产生相应的二硫代衍生物(同烯酸二阴离子)4和8。与各种亲电试剂(1当量)的反应以良好的收率得到了末端取代的酰胺。
