This shows the mechanism of the experiment performed. The reaction proceeds by an aldol condensation. Step 1: First, an acid-base reaction.
WebStep 1: Synthesis of Benzoin This reaction is a classic--the conversion of two molecules of an aldehyde to an alpha-hydroxy ketone. The reaction is known as a benzoin condensation ("condensation" because two molecules become condensed to one molecule). This reaction, which requires a catalyst, if often performed with cyanide ion. WebThe first diastereoselective synthesis of spirothiooxindoles is reported via the Michael reaction between thiooxindoles and dibenzalacetones. The reaction was conducted without any catalyst or...
