This article reports a new one-pot method for polymer preparation, which involves double click chemistry. In one pot, two click reactions take place sequentially by adding the reactants step by step. The first click reaction is to produce the monomer for

A general method for the synthesis of novel di-isoxazolines through a 1,3-dipolar cycloaddition reaction of in situ prepared bis (nitrile oxides) of terephthaldehyde and various olefins is described. The reactions are regiospecific and give high yields of

The 1,3- and 1,4-bis(3-nitrofurazan-4-yl)benzenes have been synthesized by dehydration of 1,3- and 1,4-bis(2-aminoglyoximo- 1-yl)benzenes followed by oxidation of amino groups. The 1,3- and 1,4-bis(3-nitrofuroxan-4-yl)benzenes have been prepared by nitroz

Macrocycles constitute a broad spectrum of compounds, which play a significant role in host-guest supramolecular chemistry. We have rationally designed an efficient novel synthetic method to synthesize different types of artificial receptive macrocycles containing isoxazoline or isoxazole ring systems. This method involves multiple (double, triple or quadrupole) cycloadditions between bifunctional dipoles and bifunctional dipolarophiles. We have presented our synthetic results to show the ease with which this one-pot synthetic method can be extended to synthesize different types of macrocycles such as cyclophanes, bis-calix[4]arenes and silamacrocycles. Hence, with appropriate combination of bifunctional dipoles and bifunctional dipolarophiles, the ring size of macrocycles could be controlled. This multiple cycloadditive macrocyclization will be a useful arsenal for the synthesis of various macrocycles.
