Abstract :
Titanium tetrachloride promoted Michael addition reactions of α-cyanoketene-S,S-acetals 1 with enones 2 have been developed. The polyfunctionalized 2-[1,3]dithiolan-2-ylidene-3-substituted-5-oxo-5-substituted-pentanenitriles 3 were obtained in good to high yields and the corresponding mechanism was also described.
