Cyclopropanes in Organic Synthesis
John Wiley & Sons Inc (Verlag)
978-1-118-05743-8 (ISBN)
• Provides comprehensive lists and synthetically-oriented synopses of cyclopropane chemistry review references along with publication data on applications in the syntheses of natural and related biologically active compounds
• Acts as a resource to help readers better understand cyclopropane applications for the efficient realization of synthetically important organic transformations and popular experimental procedures
• Includes new developments and up-to-date information that will lead to original methodologies for complex organic synthesis
• Stresses universality, flexibility, and experimental efficiency of a strategy based on preparing cyclopropane derivatives and performing ring cleavage reactions with inexpensive reagents
• Focuses on the synthetic potential of cyclopropane applications, for example the synthesis of natural compounds and other target-oriented syntheses via cyclopropane intermediaries, as well on their planning by retrosynthetic analysis
Oleg Kulinkovich was the head of the Department of Organic Chemistry from 1993-2003 and the head of the Laboratory of Organoelement Synthesis at Belarusian State University and visiting professor at Tallinn University of Technology. His seminal work on titanium-catalyzed cyclopropanation of carboxylic esters with Grignard reagents bearing β-hydrogen atoms (Kulinkovich reaction) is very well-known. Dr. Kulinkovich has published several reviews and original articles on organic synthesis in leading international journals.
