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.

We have developed a synthesis of a novel PI3Kγ inhibitor containing a 1,2-dihydro-3H-pyrrolo[3,4-c]pyridin-3-one scaffold. The key step in the synthesis involved a ruthenium-catalyzed [2 + 2 + 2] cyclotrimerization reaction between a diyne and an alkoxycarbonyl isocyanate, a previously unreported coupling partner in such a reaction.
