Mondal, Buddhadeb; Balha, Megha; Pan, Subhas Chandra published the artcile< Organocatalytic asymmetric spirocyclization reactions of cyclic 2,4-dienones with cyanoketones: synthesis of spiro-dihydropyrano cyclohexanones>, COA of Formula: C9H6ClNO, the main research area is cyclic dienone cyanoketone cinchona alkaloid organocatalyst spirocyclization; spiro dihydropyrano cyclohexanone diastereoselective enantioselective preparation.
The first organocatalytic asym. synthesis of spiro-dihydropyrano cyclohexanones was developed via the cascade reaction between cyanoketones and cyclic 2,4-dienones. A cinchona alkaloid-derived bifunctional primary amine catalyst in combination with N-Boc-tleucine was found to be the most effective for this spirocyclization reaction and provided the desired products in moderate to good yields with high enantioselectivities.
