identify appropriatw bond disconnect in each case. then provide the requisite carbonyl precursors ко
1. Each of the following carbonyl compounds can be prepared directly from carbonyl precursors using either an aldol or Claisen reaction. Identify the appropriate bond disconnection in each case, then provide the requisite carbony! precursors, keeping in mind that some could be from intramolecular reactions. Note that the open-ended, thick "retrosynthetic" arrow is used in chemistry to mean "is made from." 1 1 1 Duplication of this problem set for any purpose other than official Harvard Extension School business prohibited...

Identify the allylic carbons in each of the following structures. (Click on an atom to select it. Selected atoms will turn green. If you make a mistake, click on the atom again to deselect it) An allylic carbon is a carbon adjacent to a double bond. Be careful to select only the carbon atoms and not the bonds.
