Synthesize the target molecule (the one at the top) from each of
the two starting materials (each starting material is a separate
synthesis). Any additional sources of structural carbons can only
have 1 C atom at a time.

Design a synthesis for the following molecule starting from
commercially available starting materials. You may use any reagents
along the way that are commercially available. Should a subtrate
you need not be commercially available, then you need to show me
how you would synthesize it.
Pay
close attention that your design takes into account the
stereochemistry.

Show the structure of your target molecule as well as the Synthetic
schemes illustrating the two steps required for preparing it from
“allowed” starting materials. for each synthetics that indicate the
source of the experimental procedure you will follow - sources can
either be literature references or simply the course packet self.

1. Provide a complete retrosynthesis and forward synthesis of the target molecule below from the given starting materials. All carbons of the target must be from the given starting materials. You may use any reagents you find necessary. You may include more than one step over a reaction arrow, but please no more than 3 steps at a time. Please show the key intermediates in your synthesis for partial credit. (10 bonus points) For full credit, include a retrosynthetic analysis,...
