  日期：——

  The use of a simple weak inorganic base such as potassium carbonate facilitated the formation of carbon-carbon bonds through both the Henry and the Michael reactions with nitrocompounds. The application of this catalyst under environmentally friendly solventless heterogeneous conditions gave satisfactory to good yields of β-nitroalcohols, involving aliphatic and aromatic starting materials, as well

  Pyrrolidine-derived functionalized chiral ionic liquids (FCILs) have been found to catalyze asymmetric S N 1 α-alkylations of ketones and aldehydes with up to 99 % yield, >99:1 dr and 87 % ee. The FCIL catalysts enable S N 1 α-alkylations of cyclic ketones, particularly of 3- and 4-substituted cyclohexanones with excellent diastereoselectivity and good enantioselectivity, featuring unprecedented desymmetrization
