We propose that the specialized model can be used alongside the current 'all encompassing' model currently used in synthetic planning tools, and as a stand-alone idea generator for proposing retrosynthetic disconnections to a wide range of ring systems, including those previously unseen. This has implications in the pharmaceutical, agrochemical, and dye industries, to name a few, where ring systems are an important and widely used motif at the center of many marketed compounds. Furthermore, we propose that this methodology can be extended to other specialized domains within synthesis planning tasks where the data may be limited and domain specific knowledge (i.e. a specialist) is required. The methodology could also be extended to combine various data sources to increase domain specific coverage, in addition to data augmentation techniques published at the time of writing this manuscript.
