Synthetic Methods for Biologically Active Molecules

This useful reference focuses on the currently available toolbox of bio-catalysed reductions of C=O, C=C and formal C=N bonds to show which transformations can be reliably used in manufacturing processes and which still require improvements. Following an introductory chapter, chapters 2-4 present the synthetic strategies that are currently available for the reduction of C=C and C=O bonds and for reductive amination, by means of whole-cell catalysts and isolated enzymes. Chapters 5-7 go on to describe the improvements achieved thus far, illustrating the current versatility of enzymes in organic synthesis. Chapters 8-12 present the improvements brought about by the optimization of reaction conditions, and the use of particular synthetic sequences. The final chapter describes practical applications of bio-reductions for the synthesis of active pharmaceutical ingredients. With its excellent and comprehensive overview, this book will be of great interest to those working in academia and industry.
