diastereoconvergent formal nucleophilicsubstitution of bromocyclopropanes with oxygen- and sulfur-based nucleophiles is described. The reaction proceeds via in situ formation of a highly reactive cyclopropene intermediate and subsequent diastereoselective addition of a nucleophile across the strained C═C bond. Three alternative means of controlling the diastereoselectivity of addition have been demonstrated:

A compound represented by formula (I):
(wherein the symbols are the same as defined in the description), a salt thereof, an N-oxide thereof, a solvate thereof or a prodrug thereof, and medicinal use thereof.
The compound represented by formula (I) has CXCR4 antagonistic activity. It is hence useful as, e.g., a preventive and/or therapeutic agent for CXCR4-mediated diseases such as inflammatory/immunologic diseases (e.g., rheumatoid arthritis, arthritis, retinopathy, pulmonary fibrosis, and rejection reactions of transplanted organs), allergic diseases, infections diseases (e.g., human immunodeficiency virus infection and acquired immunologic deficiency syndrome), psychoneurotic diseases, cerebral diseases, cardiac/vascular disease, metabolic diseases, cancer diseases (e.g., cancer, cancer metastasis) or as an agent for regeneration therapy.

A compound represented by general formula (I):
a salt thereof, a solvate thereof, or a prodrug thereof wherein all symbols are as defined in the specification has an antagonistic activity against CXCR4 and is therefore useful as a preventive and/or therapeutic agent for CXCR4-mediated diseases, for example, inflammatory and immune diseases (for example, rheumatoid arthritis, arthritis, retinopathy, macular degeneration, pulmonary fibrosis, transplanted organ rejection, etc.), allergic diseases, infections (for example, human immunodeficiency virus infection, acquired immunodeficiency syndrome, etc.), psychoneurotic diseases, cerebral diseases, cardiovascular disease, metabolic diseases, cancerous diseases (for example, cancer, cancer metastasis, etc.), a preventive and/or therapeutic agent for cancerous diseases or infections, or an agent for regeneration therapy.
