Forward and Retro Diels-Alder Post-Lab Questions: 5-methylfuran-2 (5 H)-one (see below) is an alcohol/water sensitive compound. In the presence of an alcohol, it undergoes a process known as transesterification. Draw the structure of transesterified 5- methylfuran-2(5H)-one: 1. H CHн-он :0: Transesterification -СH3з If the reaction vessel were exposed to methanol during the course of the reflux, would a Diels-Alder reaction also take place with the transesterified dienophile from question 1? Why or why not? Draw the structure of the product...

question
If the Diels-Alder reaction is classified as a [4 + 2] cycloaddition reaction, how would you classify the cycloaddition reactions shown below? You are instructed to use 140 mg of cyclopentadiene (d = 0.80 g/mL). It is typically more convenient to measure out a volume of liquid. What volume of cyclopentadiene should be used? In the Diels-Alder reaction that you will be...
