This experiment involved the use of Fischer Esterification to create isopentyl acetate from reacting isopentyl alcohol with acetic acid and sufluric acid. 1. Provide a balanced equation to explain the evolution of gas during the sodium bicarbonate washing step. 2. The microscale synthesis of esters often uses a Dean-Stark trap. A Dean-Stark trap separates and collects water during a reaction. How would using a Dean-Stark trap during a Fisher-Esterification affect the synthesis? 3. Esters are often used in artificial flavorings....

Help with synthesis of an antibiotic macrolide.
Macrolides are large ring lactones (cyclic esters) which have been shown to have both anti-tumor and antibiotic activity. In the synthesis of an antibiotic macrolide, Compound A(C_8H_16O_3) was prepared. A was transformed into B(C_8H_14O_3) using pyridinium chlorochromate (PCC) in methylene chloride. B reacts with one equivalent of vinyl Grignard reagent to yield C(C_10H_18O_3) after workup in acidic water. If excess vinyl Grignard is used, F (shown below) is formed. C, when placed in...
