Distance(p2) returns the distance between p1 and p2. Jay is correct and so is your textbook. Diels-Alder synthesis 2 does not have a regioselectivity problem, but the reaction of an electron-rich diene with an electron-rich dienophile is often sluggish and incomplete. Now that we know all of our reactions, let's see if we can put those reactions together to synthesize some simple organic compounds. Match the major organic product with the starting material/reagent. Since carboxylic acids, esters, aldehydes and 1º-alcohols are easily interconverted, this target may be changed to the corresponding tetracarboxylic acid, as shown in the following diagram. All of these have a common origin in diethyl malonate, which can be reduced to a 1, 3-glycol and then converted into 1, 3-dibromopropane. Alcohols Practice Problems. This problem may be overcome by using chiral catalysts (enzymes or transition metal complexes) with hydrogen peroxide, but a 50% conversion is the best that can be achieved and stereoselectivity may still be a problem. Reason is they don't for carbcations readily. Consider any regioselectivity and stereoselectivity where applicable: Reactions of Alkenes Practice Problems. Q: Write a reaction sequence of 4 steps and, afterwards, write the retrosynthesis.

This alteration is easily managed by addition of bromine to cyclohexene, followed by a double elimination, yielding 1, 3-cyclohexadiene.
