This protocol provides straightforward access to construct the azetidine core through sequential Knoevenagel condensation, hydration and the C-N cyclization reaction.}, doi = {10.1039/c7ob00294g}, author = {Chavan, Santosh S. and Supekar, Mrudul V. and Burate, Pralhad A. and Rupanwar, Bapurao D. and Shelke, Anil M. and Suryavanshi, Gurunath} }
