Abstract
The morpholine promoted three-component reaction of N-alkylpiperidinone, indane-1,3-dione and 2-arylideneindane-1,3-dione in ethanol at room temperature resulted in the (1H-1,5-methanoindeno[1,2-d]azocin-12-ylidene)-1H-indene-1,3(2H)-dione derivatives in good yields and with exo-configuration.
