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; Rl is
hydrogen; C1-C6 linear or branched alkyl group optionally substituted with aryl group; halogen; or aryl group optionally substi
tuted with -OCH3, halogen, and nitro; R2 and R3 are selected from the group consisting of hydrogen, C1-C6 alkyl optionally sub
stituted 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, linear
or branched alkenyl, substituted alkenyl, alkynyl, substituted alkynyl allyl or propargyl groups consisting of 1 to 6 carbon atoms;,
with the provision that when 'm' is 1, and 'n' is zero; Rl is selected from the group consisting of hydrogen, halogen; C1-C6 linear
or branched alkyl group optionally substituted with aryl group or aryl group optionally substituted with -OCH3, halogen, and n i
tro, R2 and R3 are selected from the group consisting of hydrogen, C1-C6 alkyi 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 selected from the group consisting of halogen, C1-C6 linear or branched alkyl group optionally substituted
with heterocyclic ring of 1 to 6 ring atoms, containing one to three hetero atoms selected from oxygen, sulfur, nitrogen, wherein
the heterocyclic ring may further be substituted with halogen, alkyl, arylalkyl
