* Process Research & Development.

Process philosophy:

Innovation; fewest steps; fewest solvents; maximize productivity per step; employ through processing; minimize protecting groups; catalytic methods; avoid dangerous reagents; atom economy; minimize waste; minimize energy usage; avoid classical resolutions

Process Service:

Synthetic route design, evaluation and scouting;

Process development and optimization to reduce cost and maximize throughput;

Analytical method development for in-process control and final product analysis;

Evaluation of processes for environmental health and safety issues;

Identification of impurity profiles for raw materials, intermediates, and final products.

Case:

Steps Reagents Overall Yield Product
Initial Process 6 Expensive ,Dangerous(LAH,BBr3) 35.2% Off-white
Optimized Process 5 Cheap and safe(KBH4,AlCl3) 52.5% White(good work-up and crystallization method)
