资源简介:
The electroreductive coupling of optically active N-E-crotonoyl- and N-cinnamoylimidazolidin-2-ones and oxazolidin-2-ones with diaryl ketones in the presence of chlorotrimethylsilane gave adducts with high diastereoselectivity. The adducts were readily transformed to optically active 4,5,5-trisubstituted γ-butyrolactones by treatment with TBAF.
