In addition, the chemoinformatic analysis of 32 unprecedented macrocyclic compounds using principal component analysis PCA and principal moments of inertia PMI analysis illustrated the possibilities of the resulting macrocycles to modulate novel biological targets through occupying unique chemical space distinct from the current synthetic drugs. Chemoinformatic analysis of the resulting compound collections obtained using the CtD strategy demonstrated a higher skeletal complexity compared to conventional compound collections in terms of higher fractions of sp3-hybridized carbon atoms Fsp3 , lower clogP values, and greater numbers of stereocenters. The combination of DOS-based molecular diversity and unbiased phenotypic screening may shed light on the unraveled signaling pathways and other intricate biological processes by allowing the sustainable supply of new drug candidates and chemical probes.

The key strength of the SuRE method is that the same coupling and ring-expansion sequence can be repeated as the reactive amide functionality is regenerated in the product. The entire collection of morpholines was also studied using different chemoinformatic approaches Colomer et al. For example, Tan et al. All the library members were found being grouped in four different clusters Figure 5 , I—IV , depending on both the structure of the skeletons and side chain properties. In this work, as a further improvement in this direction, we envisioned to install quaternary stereocenters on this nucleus, as they are often present in the structure of many biologically active compounds and pharmaceutical agents Christoffers and Baro, ; Hawner and Alexakis, Hence, the DOS approach leads to an exponential increase in the molecular diversity of chemical libraries through multiple systematic branching sequences.

However, the Staudinger ketene-imine reaction, despite the possibility to introduce a quaternary stereocenter in the molecule, proved not to be a good strategy in terms of improving the Fsp3 ratio of the overall molecule, since it introduced a high number of sp2 carbon atoms due to the presence of aromatic appendages. Moreover, the successive ring-expansion SuRE strategy described by Unsworth et al. In particular, the systematic construction of diverse sp3-rich 3D polyheterocycles containing privileged substructures has been emphasized since their rigid and diverse frameworks can selectively bind with biopolymers to induce conformational changes and subsequent functional modulation.
