Mechanochemical organic synthesis. Famous philosopher Aristotle''s statement "No Coopora nisi Fluida" means ''no reaction is possible in the absence of solvent'' and that was a common belief till last few decades. However, during the 1980s the pioneering works of Toda and coworkers proved that many organic reactions of solution chemistry would be reproducible in solid state too .

Although SPPS is the strategy of choice towards long peptides so far, this study showed that ballmilling was superior to the solution synthesis when considering long peptides. Similarly, ballmilling proved far more efficient than the synthesis in solution when considering the reaction time of the coupling steps.
