Synthetic Chemistry

During its 25 years’ history, ChemDiv has developed an arsenal of proprietary approaches towards fast, tractable and, even more importantly, novel chemistries. Examples include cascade addition-cyclization, multi-component reactions, one-pot syntheses, assemblies of macrolide-mimetics, spiro– medium- and large(macro) heterocyclic systems, isosteric replacements of aminoacids, di-/tri-peptides and many other unique protocols.

Several notable advantages offered by our synthetic team include:


Our teams of highly skilled scientists have formidable experience in addressing your synthetic, medicinal, building blocks, medicinal chemistry and compound optimization needs. It is this combination of a robust science, discovery chemistry expertise and transparent business/financial models that allowed us to offer Chemistry Systems on Demand™ approach. Specifically, we provide you with a set of our validated chemistries and respective scaffolds for your assessment followed by synthesis of large or small (target/purpose-focused) custom screening compounds. Alternatively, we are happy to accommodate your chemical development ideas in order to convert them into compound libraries that uniquely suit your project needs.

  • Fast turn-around time in assessing project feasibility, cost and timing
  • Management of a project by both science and business-focused professionals
  • Development of your proprietary chemistries or compound library design based on our proprietary templates
  • Estimated 10,000 scaffolds to choose from
  • Synthetic, scale-up or medicinal chemistry and target considerations for design
  • Computational and modeling assessment of target relevance, drug-/lead-like character

Multiple considerations go into the design of templates, compound libraries and unique molecules. Naturally, ChemDiv takes into consideration and implements every specific consideration of our Clients. Additionally, key guidelines of modern discovery chemistry including both chemical and biological aspects are involved:

  • Template/screening compound novelty, and intellectual property status;
  • Drug- or lead-likeness, including lipophilicity, biomembrane/blood-brain barrier permeability, Fsp3 character, ligand efficiency vs. lipophilic ligand efficiency and (yes!) water solubility
  • Relevance to specific Biological goals, for example targets, target classes, pathways, and cellular processes
  • Diversity as compared to the developed commercial chemical space or pertinent to your specific needs
  • Synthetic considerations: feasibility, building blocks (commercial and/or project and compound library specific, including your proprietary selection)
  • Rapid expansion to launch structure-activity relationship (SAR) studies of representative molecules

At ChemDiv, we are always ready to incorporate your specific needs into every step of the design process.


Every chemical procedure is as good as its validation. At ChemDiv, we pay specific attention to this crucial step of discovery chemistry. Once the protocol is suggested and adopted, our team of chemists evaluates reagents, conditions, feasibility, scaleability and safety in a multi-parameter validation matrix. If desired, our clients may be closely involved in either contributing to or monitoring of this process. In general, validation takes 2-4 weeks in order to gain information with regard to:

  1. The general utility of the protocol or synthetic access to the molecule of interest
  2. Tentative yield(s)
  3. Feasible synthetic route(s) and potential for further detailed optimization(s)
  4. Alternative strategies aimed at improving:
    • Synthetic feasibility
    • Yield(s) of the targeted materials
    • Financial/material aspects of the work
  5. Potential to expand the procedure in order to conduct multiple compound library/ies and/or structure-activity relationship (SAR) studies
