Abstract
It was shown that isobutyraldehyde and cyanoacetic ester enter into reaction with meta-xylene initially at the fourth carbon atom with the formation of a spiropyrroline ring and then at the newly formed exomethylene bond with closure of the 1-ethoxycarbonylmethylidene-8-(2’-ethoxycarbonylmethylidene-5’,5’-dimethyl-3’-pyrrolidinylidene)-3,3,6-trimethyl-2-azaspiro[4,5]deca-6,9-diene system.
