Efficient α-alkylation and silylation of aromatic O-tert-butyldimethylsilyl ketoximes
摘要:
The a-alkylation and silylation of para substituted acetophenones, 1- and 2-indanone (O-TBS) oximes at various reaction conditions, were studied. Optimum conversions from 82% to 100% were afforded for the alkylation and silylation of these (O-TBS) ketoximes with LDA at -78 degrees C, using electrophiles, such as, methyl iodide, ethylbromide, benzyl bromide and trimethylchlorosilane.
