Indeed,theachievementsofthepharmaceutical industryareunderpinnedby moleculardesignandsynthesisofvirtuallyallthehealingdrugsubstancesthatarecurrently onthemarket,whichbenefitmankindandcurehumandiseases. Thereis,inmyview,nothingnoblerthanthisworthwhiletask. However,synthesisofthe complexfunctionalarchitecturesisnotatrivialorroutineprocess.Thisisalwaysmademore difficult on scaling up of the chemistries to comply with current standards of safety, robustness, costs, quality, and environmental impact. I, therefore, very much welcome this new textbook, Practical Synthetic Organic Chemistry: Reactions, Principles, and Techniques, which gives us an inspiring and pragmatic glimpse at the most commonly usedandeffectivesynthesisproceduresonscale. Thisuniquetextbookhasbeenwrittenby experts in the field and provides an insight and critique of the key effectivemethods for molecularassembly.Itwillbeagreatstartingpointforanyonedevelopingtheircareerinthis worthyindustry. The organization and chapter titles reflect a refreshing approach to explaining a complicated science covering all the major bond construction methods and functional controlelementsnecessaryformodernsyntheticplanningandexecution. Theauthorshaveincorporatedchaptersonimportanttopicssuchastheeffectivenessof rearrangementprocesses,radicalreactions,accesstochirality,andgreenchemistry,which are not captured as a group in more traditional texts.
