Synthetic Aspects of Photochemical Electron Transfer Reactions

摘要: The major applications of organic photochemical processes to synthetic problems have date focused for the most part on use photocycloadditions and electrocyclizations in preparation strained ring compounds target systems or key intermediates. utility these methods selected preparative sequences construction natural and/or theoretically interesting products has been reviewed.(1) In general, excited-state reactions share several unique features which make their chemistry particularly advantageous. For example, serve as useful generating carbon-carbon bonds which, due high energy content, are capable participating facile cleavage leading desired Similarly, lead installation difficultly prepared cyclic units from more readily available acyclic precursors. is further broadened by predictable regiochemical stereochemical courses utilizing simple molecular orbital methods. Other classes used introduction interconversion functionality systems. Thus, appear compatible with criteria established evaluation synthetically gound-state transformations.
