• Combinatorial Synthesis of a Series of Esters

  107194 Combinatorial Synthesis of a Series of Esters 1. Why are the crude ester mixtures washed with aqueous NaHCO3? 2. You wish to test 9 esters for antitumor activity. One and only one of the 9 esters will actually have antitumor activity.

• Explaining reactivity of amines with carboxylic acids versus esters

  A brief explanation is given to explain why carboxylic acids don't undergo nucleophilic addition with amines but esters do.
