Not since German chemist Friedrich Wöhler demonstrated in 1828 that an organic compound‚ urea‚ could be synthesized from inorganic precursors‚ ammonium and cyanic acid (Kinne-Saffran and Kinne‚ 290)‚ has the line between organic and inorganic or‚ in this case‚ biology and chemistry‚ been blurred as it has been in Addy Pross’ book What is Life? How Chemistry Becomes Biology. In it‚ Pross dispels the traditional belief that life’s evolution and origin must be subdivided into a chemical phase followed

Abstract Introduction The acylation of the α carbon position of a carbonyl group is one of the greatest breakthroughs that has benefited chemists in organic synthesis particularly when in need of building a carbon skeleton of interest in a molecule. For one to be able perform this acylation technique‚ there are two mar approaches which are employable. The first method involves the deprotonation of the α-Carbon atom which has a pKa known to be ̴20 through the use of a strong base for instance
