“…In this regard, we and others have recognized the usefulness of solid-supported olefin cross-metathesis for generation of biologically relevant molecules [ 27 , 28 , 29 , 30 , 31 ], including a comprehensive study to understand the process [ 32 , 33 ]. From the viewpoint of green chemistry, using solid-phase synthetic sequences allows a significant reduction in solvent waste, since purification is performed by phase separation, avoiding chromatographic isolation of products which requires a large consumption of organic solvents [ 34 ].…”
