This dessertation deals with the organocatalytic kinetic resolution of activated nitroallylic acetates 56a-h and 2-methylcyclopentane-1,3-dione 55 via SN2 reaction to produce chiral products 65a-h with a high enantiomeric excess (up to 90% ee) and a moderate chemical yield (41%) and acetates 56a-h was recovered obtained with high chemical yield (46%) ,but with a low enantiomeric excess (20% ee). Exclusive screening of various organocatalyst in our laboratory led to the conclusion that pyrrolidinyl-camphor based bifunctional organocatalyst catalyses the reaction at room temperature with in 6h in CHCl3. The structure of the product was fully characterized and the absolute configuration of product 65b was further unambiguously determined by single-crystal X-ray analysis.
