For decades, chemistry has been modeled on billiard ball reactions. However, the chemistry of the future will undoubtedly involve prior, probably stereospecific, complexing of reactants before reaction per se occurs. The cyclodextrins are the first organic compounds found that show the ability to complex other organic compounds. Their stereospecificity is limited, although they do exhibit stereospecific reactions. As noted above, they do catalyze many organic reactions, in some ways mimicing the action of enzymes. Just as enzymes do not engage in billiard ball chemistry, the cyclodextrins do not engage in billiard ball chemistry (usually). The fact that enzymes can achieve such high rates of reaction indicates that prior complexing followed by reaction must be the chemistry of the future.
