Synthesis of functionalized isoxazole-oxindole hybrids via on water, catalyst free vinylogous Henry and 1,6-Michael addition reactions

Various 3-substituted-3-hydroxy isoxazole-oxindole hybrids were synthesized via the vinylogous Henry reaction of 3,5-dimethyl-4-nitroisoxazole and isatin using water as a reaction medium under catalyst free conditions at 50 C. Systematic studies were carried out to understand the role of the water on the reaction by using D2O, brine, ethylene glycol and PEG-400 as a reaction medium along with organic solvents. Among all of these, water (0.170 mol concentration) was found be more efficient giving desired products in 82-99% yields in 45-120 min. Further the quaternary centre (3 alcohol) generated was used for the creation of a double bond which was again used for a 1,6-Michael reaction to produce highly functionalized isoxazole-oxindole derivatives.

Metal-carbonyl-Induced Reaction of Isoxazoles. Ring Cleavage and Reduction by Hexacarbonylmolybdenum, Pentacarbonyliron, or Nonacarbonyldi-iron

In the presence of and water the isoxazoles (1a-f) undergo thermally induced reductive cleavage of the N-O bond to give beta-amino enones in good yield.Similar results were obtained by the use of and water with photoirradiation, or of and water with heating.A mechanism involving an N-complexed isoxazolepentacarbonylmolybdenum or isoxazoletetracarbonyliron, and a – or -complexed (beta-oxo vinyl)nitrene intermediate is proposed for the reactions.The complexed nitrene moiety could be reduced by the central metal in the presence of water to give amine.Furthermore, treatment of 2-benzoyl- 3-phenyl-2-H-azirine (8a), which is an isomer of 3,5-diphenylisoxazole, with the metal carbonyls and water also resulted in the formation of a beta-amino enone possibly via the corresponding complexed (beta-oxo vinyl)nitrene.An N-complexed isoxazole-pentacarbonylmolybdenum intermediate was prepared by the photoreaction of with 3,5-dimethylisoxazole.Its characterization, and chemical transformations, have been carried out to investigate the proposed mechanism.
