Go through these synthesis problems and just need to develop a few general strategies for each of these molecules.
Your approach should begin with the kinds of reagents that one can typically buy from a commercial supplier. For the purposes of this question, you can assume that you have access to:
(a) simple alkyl, alkenyl or alkynyl reagents with up to 4 carbon atoms, for example:
(b) aryl or heteroaryl molecules with a maxiumum of 2 simple substituents (each containing ≤ 1 carbon atoms), e.g.:
(c) simple 5- or 6- membered rings, for example:
(d) other reagents or catalysts that we've seen in class.
You will not have access to organotin or organoborane compounds, so you'll have to make those yourself.
