The reaction of 2‐aroyl‐3,3‐bis(alkylsulfanyl)acrylaldehydes and hydroxylamine hydrochloride: Facile synthesis of differently substituted isoxazoles

2-Aroyl-3,3-bis(alkylsulfanyl)acrylaldehyde was utilized for the synthesis of three different isoxazoles by reacting with hydroxylaminehydrochloride. We synthesized differently substituted isoxazoles like (aryl)[5-(methylsulfanyl)-4-isoxazolyl]methanones, 3-(methylsulfanyl)-5-phenyl-4-isoxazolecarbonitriles and 5-aryl-3-(methylsulfanyl)-4-isoxazolecarbaldehyde oximes in good yields by varying the substratereagent stoichiometry and temperature of the reaction medium.
