Construction of chiral complex molecules continues to be a challenge for organic chemists all over the world and to address this challenge numerous methodologies have been developed. 1,3-Dipolar cycloaddition reactions is one such simple and elegant method, which can be employed towards the construction of chiral heterocycles. The ability to construct multiple stereocenters in one operation is one of the salient features of dipolar cycloaddition reaction. Asymmetric dipolar cycloaddition via chiral Lewis or Bronsted acid catalyzed processes is aided by the development of various templates, which provide points of attachment for these catalyst. Application of acyl imidazoles as multifunctional templates has been investigated for Lewis and Bronsted acid catalyzed 1,3-dipolar cycloaddition of azomethine imines and nitrones. Chapter 1. A review of 1,3-dipolar cycloaddition towards to construction of chiral nitrogen containing heterocycles is discussed in this chapter. This chapter intends to provide the reader a current state of asymmetric 1,3-dipolar cycloaddition. Chapter 2. Development of exo and enantioselective Cu(II) catalyzed azomethine imine cycloaddition to pyrazolidinone acrylates is discussed in this chapter. The key issues approached in this chapter includes impact of metal geometry on diastereoselectivity as well as effect of N-l and C-5 substitution on enantioselectivity of cycloadducts. Investigation into the scope and limitation of azomethine imines and dipolarophiles has also been discussed. Chapter 3. This chapter introduces acyl imidazoles as multifunctional template for asymmetric azomethine imine cycloaddition. Limitation of substrate scope for azomethine imine cycloaddition encountered in the previous chapter has been resolved by the use of acyl imidazoles as templates. Synthesis of complementary diastereomers of azomethine imine cycloadducts via Lewis acid and Bronsted acid catalyzed reactions has been discussed in this chapter. Chapter 4. This chapter highlights the application of acyl imidazoles as template for first Bronsted acid catalyzed exo and enantioselective nitrone cycloaddition to electron deficient olefins. Study of appropriate chiral Bronsted acid and investigation of breadth and scope of nitrones and dipolarophiles has also been discussed here. Chapter 5. This chapter address one of the most challenging aspect of synthetic organic chemistry namely the construction of chiral quaternary stereocenters. This study highlights chiral Bronsted catalyzed nitrone cycloaddition to p,|3-disubstituted-a,P-unsaturated acyl imidazole leading to the formation of isoxazolidines with chiral quaternary stereocenter. This methodology is useful for the construction of chiral fluorinated heterocycles.
