Organosilicon synthesis of isocyanates: I. Synthesis of isocyanates of the furan, thiophene, and mono-and polyfluorophenyl series
摘要:
A convenient synthesis of known and unknown isocyanates of the furan, thiophene, and mono- and polyfluorophenyl series, involving silylation of starting amines with hexamethyldisilazane or chlorotrimethylsilane, followed by phosgenation of the resulting N-silyl-substituted amines. An unusual high-temperature rearrangement of 3-(methoxycarbonyl)-4,5-dimethylthiophene-2-yl isocyanate into its 5-ethyl isomer. ortho-Fluorine substituent in anilines decreases the yield of isocyanates, whereas 2,3,5,6-tetrafluorophenyl isocyanate exists for only a short time as a 5% toluene solution.
Transientreceptorpotentialmelastatin8 (TRPM8) ion channel represents a valuable pharmacological option for several therapeutic areas. Here, a series of conformationally restricted derivatives of the previously described TRPM8antagonist N,N′-dibenzyl tryptophan 4 were prepared and characterized in vitro by Ca2+-imaging and patch-clamp electrophysiology assays. Molecular modeling studies led to
