Forinstance, 1,3 dipolar cycloadditionsareelectronicallyequivalent to Diels Alder reactions and are among the most common 5-membered ring-forming systems. In addition they usually proceed with a high degree of stereo- and regio-control.It is therefore, not surprising that synthesis of many important classesofheterocycles,includingthoseofusefulbiologicallyactivemolecules, haveutilized cycloadditionsteps intheir formation.Furthermore,manyhe- rocyclesserve as intermediates in the synthesis of polyfunctional molecules. In this volume we present ve selected contributions by well-known - thors, each an authority in his eld. The rst chapter deals with construction ofisoxazolines(dihydroisoxazoles)via1,3-dipolarcycloadditionsofnitronates or of nitrile oxides generated from nitroalkanes. This includes inter- as well as intramolecular processes. Many of these heterocycles possess important synthetic and biological properties and are shown to lead to stereo- and - gioselectiveintroductionofmultifunctionalmoleculessuchasaminoalcohols, -amino acids, aldols, nitriles, and others.…
