Ethyl 2-chloroacetoacetate
Based on 1 Customer Validation
Ethyl 2-chloroacetoacetate (A 21960) is a chloroacetoacetate ester and also an alkylation building block for synthesis. Ethyl 2-chloroacetoacetate can serve as a starting material to undergo diazotization with aniline to generate a phenyltriazole-derived N-capping group, followed by cyclization with acetaldoxime. Ethyl 2-chloroacetoacetate can be used to synthesize steroidal thiazole and oxazole derivatives, which exhibit antimicrobial activity against Staphylococcus aureus, Listeria monocytogenes, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, and Cryptococcus neoformans.
