%Amino-/.%arylacrylonitriles are commonly prepared by the nucleophilicadditionreaction of acetonitrile anion, prepared by in-situ deprotonation of acetonitrile, to aromatic nitriles. As acetonitrile is a very weak acid (pKa = 31.3)", strong bases such as r-BuOK'? or NaNH2 are The nucleophilicreactions usually give poor yields and require long reaction times (at least 10 hrs). Application of Ultrasonically

Substituted (1,2-diarylethyl)amides have been prepared and evaluated for their ability to inhibit microsomal acyl-CoA:cholesterol acyltransferase activity in vitro and to lower hepatic cholesteryl ester content in vivo in a cholesterol-fed hamster. Simple unsubstituted (diarylethyl)amides were potent inhibitors in vitro but showed poor activity in vivo. Introduction of polar groups at specific locations

Synthesis of β-ketonitriles, α,β-alkynones and biscabinols from esters using tert-butoxide-assisted C(O)–C (i.e., acyl–C) coupling under ambient conditions
We demonstrated the synthesis of beta-ketonitriles, alpha,beta-alkynones, and biscarbinols using tert-butoxideassisted C(C=O)-C (i.e., acyl-C) coupling of esters under ambient conditions. tert-Butoxide-assisted C(C=O)-C (i.e., acyl-C) coupling of esters with cyanomethylenes and acetylenes under transition metalfree ambient conditions gives beta-ketonitriles, alpha,beta-alkynones and/or aryl bis(phenylethynyl)carbinols in moderate-to-good yields. It is noteworthy that this is a rapid, facile, and efficient process under ambient conditions, and use of cheap and stable starting materials. (C) 2013 Elsevier Ltd. All rights reserved.
