Synthetic organic chemistry currentiy requires a wide range of reactions that should proceed with high degree of enantio-,regio-,and chemo-selectivity and result in high yield of products. In this context,the use of enzymes as catalysts for buildins the sythons of biologically active compounds.The enzyme-assisted organic synthesis involves a relatively simple procedure and compounds in a fairly high state of purity are obtained.The following processsm are discussed in this article,factors involved in controlling and predicting this structural specificity and storeospecificity of synthetically useful enzymes,includins pig liver sterase,exploring regioselectivity,enantiomeric spocificity and prochiral stereospecificity of hydrolases,transferases and oxido-reductase catalized reactions,including enzyme-catalized hydrolysis of alcohols and esters,lipase catalysed trans-esterification with activated and nonactivated acyl donors in organic solvents, reduction of carbonyl compounds and activated double bonds,finally,oxidition of sp￣3 carbons and alkenes,also including Baeyer-Villiser Oxiditions.The use of these biocatalytic metheds for the stereocontrolled preparation of important target structures is reviewed and some of the future development of the biotransformation area are discussed. 18 references are presented.
