Lead Diversification tool Box 2

HepatoChem has developed several kits for lead diversification for the C-H functionalization. This chemistry offers many possible transformations including hydroxylation, acetoxylation, methoxylation, and halogenation among others. This chemistry can be sometimes difficult.
The HepatoChem kits is offering you a rapid, practical and cost-effective solution for analogues obtaining. They enable the parallel screening of a selected set of catalytic conditions focusing on generating diversity with an approach totally orthogonal and complementary to conventional synthetic methods.

HepatoChem proposes different kits:

  • Alkoxylation and Acetoxylation kits
  • Fluorination kit
  • Biomimetic Oxidation kit
  • Sulfinate Alkylation reagent kit
  • Photocatalytic alkylation diversification kit

 

Alkoxylation and Acetoxylation Kits

Diversity Kit : 4 different functionalizations

C-H Alkoxylation is one of the most C-H functionalization described in literature. HepatoChem kit is designed to enable conveniently the screen of both Alkoxylation and Acetoxylation reaction conditions. It uses PdOAc2 as catalyst with several oxidants and additives.

Kit HCK1007-01-001 (article 9H4350)
Substrate solution is prepared in DMF (to facilitate the screening of solvents) and added to all four for solvents. Screen the four solvents (methanol, ethanol, isopropanol and acetic acid) with three reaction conditions (different salts). 10mol% Pd(OAc)2, 1 equiv PhI(OAc)2.

Salt Effect on C-H functionalization

Optimisation Kit: 5 differents salts

It has been reported that salt can influence C-H functionalization. HepatoChem kit is designed to enable the screen of several salts simultaneously. This kit contains 5 different salts CuOAC2, Ag2CO3, K2CO3, Cs2CO3, MgSO4.

Kit HCK1007-01-002 (article 9H4360)
Screen 1 solvent with 12 reaction conditions. 10 mol% PdOAc2, 1 or 2 equivalents of PhIOAc2 with 5 differents salts. Prepare one solution in solvent or mixture in DMF if solubility issues.

Fluorination Kit

Fluorination is one of the most interesting C-H functionalization described in literature. HepatoChem kit is designed to screen fluorination reaction conditions using PdOAc2  as catalyst in presence of common fluorine sources : Silver Fluoride AgF, 1-fluoro-2,4,6-trimethyl-pyridinium triflate (TMPyF), SelectFluor®, N-fluorobenzenesulfonimide (NFSI) and Bis(tert-butylcarbonyloxy iodobenzene (PhIOPiv).

Kit HCK1008-01-001 (article APQ9X0)
This kit includes 2 sets of reagents ; catalyst and oxidant are mixed in the same vial

12 conditions with AgF, TMPyF, Selectfluor and NFSI

Biomimetic Oxidation Kits

HepatoChem has developed a revolutionary way to screen, optimize, and produce metabolites directly from drug candidates. The BMO kit exploits an optimized panel of catalytic chemical reaction conditions with organometallic catalysts. This tool enables to mimic the suite of cytochrome P450 enzymes (CYP) present in human hepatocytes.
HepatoChem BMO kits enable, in three simple steps, synthesis of metabolites directly from the parent drug.

Biomimetic Oxidation Kits

Sulfinate Alkylation Reagent Kit

The sulfinate alkylation reaction described by Prof. Baran is a powerful late stage functionalization tool. HepatoChem kit enables to produce analogues of the lead compound in mg quantities using 6 different alkylation reagents. Each vials contains 100µmol of sulfinate alkylation reagent and a stirring bar to react with 50µmol of substrate. The C-H functionalization will mainly occur on electron-deficient heteroarenes at one or several positions.
