Concertedness of 1,3-dipolar cycloadditions

Journal of Chemical Education, 1984
The 1,3-dipolar cycloaddition is the union of a 1,3-dipole with a multiple bond system (a dipolarophile) to form a five-membered ring; the process is regarded as one of the most general methods for the synthesis of five-membered heterocycles.

1,3-dipolar cycloadditions with porphyrins

2009
The objective of this work is to use 1,3-dipolar cycloadditions to synthesize novel aromatic compounds based on meso-phenyl substituted porphyrins. These compounds are potential photosensitizers for use in photodynamic therapy. Tetraphenylporphyrins with a variety of substituents were reacted with selected 1,3-dipoles.
