Full mechanism for the synthesis of diacetone mannose from D-mannose, ferric chloride and excess acetone
Homework Answers
Drawn below is a possible mechanism for the formation of diacetone mannose starting with D-mannose. The first step is FeCl3 (Lewis acid) forms a bond with a molecule of acetone to generate a more electrophilic carbon center. The mannose Oh then acts as nucelophile and attacks this carbonyl carbon center. The process is repeated to form mon-acetone mannose and then a diacetone mannose derrivative.
