Stereoselectivity
is a major issue in synthetic organic chemistry. The use of chiral reagents and
catalysts can solve the problem to a greater extent. But there are problems
associated with the use of these chemicals as they may be expensive, hard to
get, and most of the time not friendly for the environment. Enzymes, the
biological catalysts, have been used as chiral catalysts for carrying out
stereoselective reactions, mainly because of their specific nature. Enzymes are
proven to be environmentally benign.
