Recent Advances in Azomethine Ylide Chemistry

摘要: Publisher Summary Azomethine ylides are planar molecules composed of one nitrogen and two terminal sp2 carbons. At most, four geometrical isomers possible for these transient molecules. Their cycloadditions to olefin or acetylene dipolarophiles give rise the formation sets carbon-carbon bonds in a single step. Because structural complexity azomethine ylide itself compared other dipoles stereochemical selectivity cycloadditions, number stereoisomers cycloadducts. These points make most attractive 1,3-dipoles, both fields chemistry synthetic organic chemistry. can be classified groups according their structure. This chapter concentrates on basic ylides, acyclic order catch generalized concepts involved Accordingly, it also deals with recent advances covering its preparation, intramolecular applications.
