The schemes below give possible 
  syntheses of the targets. There are of course other variations. The first part 
  for each compound gives a "retro-synthesis", the "plan" and then the required 
  forward synthesis with reagents is given. Red arrows try to show carbon-carbon 
  bond forming reactions, blue arrows are functional group manipulations. The 
  blue text rationalise the retrosynthetic analysis and information about important 
  reactions are given in green.

  

 

(note that there are several good alternatives for this compound, for example, the bromide and the carbonyl could switch sides, or a Wittig reactions could be used, see below for an example of that)
