A compound represented by the following general formula (I) and a pharmacologically acceptable salt thereof:
wherein R1 represents hydrogen atom, an alkyl group, a substituted alkyl group and the like; R2 and R3 represent hydrogen atom, an alkyl group, a substituted alkyl group, an alkoxyl group and the like; X represents —CH2—, —O—, or —NH—; A represents the following group (II):
[in which R7 and R8 represent hydrogen atom, an alkyl group, an acyl group, an alkoxycarbonyl group and the like; R9 and R10 represents hydrogen atom, a halogen atom, hydroxyl group, phenyl group, an alkyl group and the like] and the like; and E represents hydrogen atom and the like, which has inhibitory activity against carboxypeptidase B and is useful for therapeutic and/or preventive treatment of a thrombotic disease.
to excellent yields. We have prepared a library of protected amines and tertiary alcohols that give, upon cyclization with alkynes, a representative set of heterospirocycles and illustrate reaction compatibility with diverse functionalgroups. A change in catalytic activity is possible by modifying the solvent, and two original tricyclic spirocycles were synthesized in a tandem reaction.
