A three-component reaction for the synthesis of substituted anilines by a gold(i)-catalyzed domino reaction was developed. Cationic gold catalysts selectively and sequentially activated two different alkynes, which were involved in pyrrole synthesis and subsequent Diels-Alder reaction. The sequential formal (3 + 2) annulation/Diels-Alder reaction of three components provided a variety of substituted anilines in a modular fashion. Moreover, utility of the aniline products was demonstrated by derivatization to substituted benzoxazines, which are pharmaceutically important heterocycles.

Novel carbamate derivatives which are useful as drugs because of inhibiting activated blood coagulation factor X and thus exerting an anticoagulant effect. Compounds represented by the formula: wherein R1 represents a group represented by the formula: (wherein Y1 represents CH=CH, etc.), which may be substituted, etc.; the ring A represents an oxo-substituted nitrogen-containing heterocyclic ring which may be further substituted; R2 represents a hydrogen atom, optionally substituted C1-4 alkyl, etc.; R3 represents optionally substituted C1-4 alkyl, etc.; and Z represents an optionally substituted nitrogen containing heterocyclic group, etc., or salts thereof.
