Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Safety of 3,6-Dichloropyridazine. Introducing a new discovery about 141-30-0, Name is 3,6-Dichloropyridazine
The present invention is concerned with compounds of formula STR1 the N-oxide forms, the pharmaceutically acceptable acid addition salts and the stereochemically isomeric forms thereof, wherein . dbd.a. sub.1–a 2 =a 3–a 4 = is a bivalent radical of formula . dbd.N–CH=CH–CH= (a), =CH–N=CH–CH= (b), = CH–CH=N–CH= (c), =CH–CH=CH–N= (d) , wherein one or two hydrogen atoms can be substituted by halo, hydroxy, C. sub.1-6 alkyl or C. sub.1-6 alkyloxy; R 1 is hydrogen or C 1-6 alkyl; R 2 is hydrogen or C 1-6 alkyl; R 3 is hydrogen or C. sub.1-6 alkyl; Alk. sup.1 is C 1-5 alkanediyl; Alk 2 is C 2-15 alkanediyl; Q is a five-or six-membered heterocyclic ring containing at least one nitrogen atom or a radical of formula–C(NR 5 R 6). dbd.C–R 4 wherein R 4 is hydrogen, cyano, aminocarbonyl or C. sub.1-6 alkyl; R 5 is hydrogen, C 1-6 alkyl, C 3-6 alkenyl or C 3-6 alkynyl; R 6 is hydrogen or C 1-6 alkyl; or R 5 and R 6 taken together may form a bivalent radical of formula–(CH. sub. 2) 4–or–(CH 2) 5–.
Pharmaceutical compositions, preparations and use as a medicine are described.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 141-30-0 is helpful to your research.Safety of 3,6-Dichloropyridazine
