The novel biotin conjugated glaucocalyxin A analogs as potential activity-based protein probes were synthesized with good yields via Cu(I) in situ-catalyzed azide-alkyne cycloaddition. Cu(I) in situ was good solvated under the optimized condition and shown high catalytic activity. The approach efficiently constructs the even longer linker containing 1,2,3-triazole nucleus between bifunctional groups with the advantages of high regioselectivity and operational simplicity.

Key words: biotin tag, glaucocalyxin A, activity-based probe, Cu(I) in situ catalysis, azide-alkyne cycloaddition
