It was decided to investigate the routes from limonene to paracetamol more closely to see if any useful reactions could be predicted in this area of chemistry. For this section of the work usefulness was defined as a reaction which reduces the number of steps taken to carry out the conversion of limonene to paracetamol, i.e. one that provides a "short cut". Alternatively also accepted was a prediction that leads to an increase in the number of efficient paths available to carry out the synthesis, i.e. one that opens up chemical space, providing more options. Seeing as the previous chapter worked on the assumption that five steps were required to carry out the synthesis, a more efficient path was taken to be a path with a length of four or less steps.
