英文摘要: A mild Michael addition of glycine imines to aromatic-nitroalkenes catalyzed by 10 mol% DBU with LiOTf as an additive was developed. In most cases, the products could be obtained in good yields (up to 96%) with moderate to good diastereoselectivities (up to 10:1). The selectivity for syn adduct can be reversed to anti when the R group of glycine imines was changed from methyl or ethyl to tert-butyl.
