  • Patent number: 8865910
    Abstract: Invention provides antitubercular compounds selected from propargylated 1,2,3 triazoles of Formula I, wherein, X is sulfur(S) or a sulphone (A), n, m represent independently an integer O or 1, with the provision that when ‘n’ is 1, ‘m’ is 1; R1 is hydrogen; C1-C6 linear or branched alkyl group optionally substituted with aryl group; halogen; or aryl group optionally substituted with —OCH3, halogen, and nitro; R2 and R3 are selected from the group consisting of hydrogen, C1-C6 alkyl optionally substituted with heterocyclic ring of 5 to 6 ring atoms containing one to three hetero atoms selected from oxygen, sulfur, nitrogen, which may be substituted with alkyl, arylalkyl, linear or branched alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, or allyl or propargyl groups consisting of 1 to 6 carbon atoms; Z is C1-C6 alkyl optionally substituted with heterocyclic ring of 1 to 6 ring atoms, containing one to three hetero atoms selected from oxygen, sulfur, nitrogen, which may be substituted with arylalkyl,

  • Patent number: 8841296
    Abstract: This invention provides novel substituted 1,4-dioxa-8-azaspiro[4,5]decane compounds of the general formula (1), wherein R1 is selected from phenethyl, 4,6-dimethoxypyrimidin-2-yl and (2-chloro-5-thiazolyl)methyl and R2 is selected from the group consisting of hydroxy, 4-bromo-2-chlorophenoxy, morpholin-4-yl, (2-chloro-5-thiazolyl)methyloxy, benzyloxy, phenylsulfanyl, benzotriazol and 5-chloro-2-fluoroanilino. The present invention also relates to a process for the preparation of novel substituted 1,4-dioxa-8-azaspiro[4,5]decanes of general formula (1). The novel substituted 1,4-dioxa-8-azaspiro[4,5]decane of general formula (1) has fungicidal activity.
