One-pot synthesis of oxazolidinones and five-membered cyclic carbonates from epoxides and chlorosulfonyl isocyanate: theoretical evidence for an asynchronous concerted pathway
Demir, Esra; Sari, Özlem; Çetinkaya, Yasin; Atmaca, Ufuk; Erdem, Safiye Sağ; Çelik, Murat (Beılsteın-Instıtut, 2020)The one-pot reaction of chlorosulfonyl isocyanate (CSI) with epoxides having phenyl, benzyl and fused cyclic alkyl groups in different solvents under mild reaction conditions without additives and catalysts was studied. ... -
Synthesis of Benzoxazole-2-carboxylate Derivatives: Electronic- and Position-effect of Functional Groups and Computational Modeling of the Selectivity for Oxazole Ring
Kuzu, Burak; Sarı, Özlem; Erdem, Safiye Sağ; Algül, Öztekin; Mengeş, Nurettin (John Wiley and Sons Inc, 2021)In this study, Mitsunobu reagent, DEAD (diethyl azodicarboxylate) and PPh3, and ethyl-oxalamide derivatives of 2-aminophenol were reacted under mild reaction conditions. As a result of the cyclization reaction, benzoxazole ...
