A task-specific basic ionicliquid, [Bmim]OH, has been introduced as a catalyst for the aza-Michaeladdition of aromaticamines and N-heterocycles to cyclic or acyclic ketones under neat conditions. The catalyst can be recycled for subsequent reactions without any appreciable loss of efficiency.

hydroalkoxylation of allylic alcohols catalyzed by a simple catalyst Y(CH2SiMe3)3(THF)2 has been developed, providing a variety of γ-amino and γ-alkoxy alcohols in good yields under mild conditions. Moreover, this protocol is applied to the synthesis of drug molecules Propipocaine and Proroxan. The rare-earth catalyst features readily available, wide substrate compatability, exclusive anti-Markovnikov selectivity
The present invention relates to antibody molecules against anticoagulants, in particular dabigatran, and their use as antidotes of such anticoagulants.

A novel cross dehydrogenative coupling (CDC) reaction of N,N-dimethylanilines with methyl ketones by cooperative copper and aminocatalysis has been developed, which leads to the formation of beta-arylamino ketones in 42-73% yields. Moreover, the copper-catalyzed alkylation of free (NH) indoles with N,N-dimethylanilines via CDC reaction is also presented, affording alkylated indoles in 52-78% yields.
