    Abstract: PROBLEM TO BE SOLVED: To provide a compound comprising a heterocyclic skeleton, useful as a nonmetallic asymmetric catalyst, capable of performing a highly stereoselective asymmetric conjugate addition reaction of a high yield and a reaction of forming a carbon-nitrogen bond; and to provide a method of producing a compound using the same as an asymmetric catalyst. SOLUTION: There are provided the compound comprising a heterocyclic skeleton represented by formula (I), a tautomer thereof, and their salts. In the formula, R 1 and R 2 each represent an alkyl group, an aryl group or the like; the ring A represents an imidazole ring condensed with an aromatic ring that may contain a substituent, or a pyrimidine-4-one ring condensed with an aromatic ring that may contain a substituent; R 3 and R 4 each represent an alkyl group, a lower alkenyl group, a lower alkynyl group, or an aryl group, provided that R 3 and R 4 together with carbon atoms each binding thereto may form an isocyclic ring that may contain a substituent or a heterocyclic ring that may contain a substituent; and R 5 and R 6 may be the same or different and each represent a hydrogen atom or a lower alkyl group that may contain a substituent.
