Chem4D03 Assignment 3 (for Oct. 30, 1998)

This assignment is the "short and snappy" variety. I would like you to propose some mechanisms, give some reagents and attempt to synthesize some molecules.

1)

a) Give reagents for the following reactions (A-I)

b) Show the mechanisms of conversion of 2-6.

c) the conversion of 5 to 6 is accompanied by the formation of 7. Why?

Do ONE of the TWO following problems

2) Starting from c5 or less, show how to make the following molecule using 2 completely different strategies.

OR

Starting from c5 or less and any reagent, (and using the compound from 2) if you want), show total syntheses of the 2 following compounds.
