Synthesis and thiocyanation of N-alkyl(trifluoromethyl)sulfonyl 1,4-benzoquinone monoimines
摘要:
New N-alkyl(trifluoromethyl)sulfonyl 1,4-benzoquinone monoimines were synthesized, and their thiocyanation gave 5-alkyl(trifluoromethyl)sulfonylamino-1,3-benzoxathiol-2-ones. An intermediate thiocyanation product, 5-trifluoromethylsulfonylamino-1,3-benzoxathiol-2-imine, was isolated for the first time.
Disclosed herein are monomeric compounds having the formula: ##STR1## wherein: R and R.sup.1 are independently hydrogen, halide or alkyl; R.sup.2 and R.sup.3 are independently hydrogen, alkyl, cycloalkyl, aryl or aralkyl; q is 0 or 1; and Ar is arylene, and a method of preparing same. These monomers can be homopolymerized or copolymerized with one or more other monomers to yield polymers having desirable solubility characteristics. In particular, copolymerizable ethylenically unsaturated monomers can comprise aldehyde-containing vinylaryl ethers, to yield crosslinkable polymers useful in relief image materials or as binders in photographic layers.
Provided herein are compounds of the formula (I):
as well as pharmaceutically acceptable salts thereof, wherein the substituents are as those disclosed in the specification. These compounds, and the pharmaceutical compositions containing them, are useful for the treatment of metabolic diseases and disorders such as, for example, type II diabetes mellitus.
