Bull's approach to substituted oxetanes.31 A) Synthesis of an exemplar oxetane (R=Bn, which was virtually removed before the computational study). B) Other scaffolds that were combined with 28 small amines to yield a virtual library of amides (see the Supporting Information). C) PMI plot of the 61 fragment‐like compounds found in the virtual library (black), 257 fragments randomly selected from the e‐molecules database (light gray) and 261 fragments randomly selected from the GDB‐17 database (dark gray). A plane‐of‐best‐fit analysis (Ref. 30) is also provided in the Supporting Information.
