A convenient route to mono-alkyl substituted phosphanylboranes HRP-BH2- NMe3, prospective precursors to poly(alkylphosphinoboranes)
A simple method is reported for accessing borylphosphonium iodides [RH2P–BH2∙NMe3]I (1a: R = Me, 1b: R = Et, 1c: R = Pr) by the addition of iodoalkanes to PH2–BH2∙NMe3. Complexes 1a-c were characterized by multinuclear NMR spectroscopy, and 1a and 1b were characterized by single crystal Xray diffraction. It was possible to synthesize the Lewis base stabilized organosubstituted phosphanylborane ...
متن کاملA convenient route to symmetrically and unsymmetrically substituted 3,5-diaryl-2,4,6-trimethylpyridines via Suzuki–Miyaura cross-coupling reaction
A series of differently substituted 3,5-diaryl-2,4,6-trimethylpyridines were prepared and characterized using the Suzuki-Miyaura coupling reaction with accordingly selected bromo-derivatives and arylboronic acids. The reaction conditions were carefully optimized allowing high yield of isolated products and also the construction of unsymmetrically substituted diarylpyridines, difficult to access...
متن کاملSynthesis and biological evaluation of diversely substituted indolin-2-ones.
The synthesis of indolin-2-one derivatives substituted in the 3-position by an aminomethylene group bearing either an ornithine or a lysine residue is described. The inhibitory activities of these compounds toward a panel of eight kinases were examined. Furthermore, the antibacterial activities of the prepared compounds were tested against two Gram-positive bacteria Bacillus cereus and Streptom...
متن کاملThe Neber route to substituted indoles.
Two complementary procedures have been developed for the conversion of the oximes of alpha-aryl ketones to azirines. On heating, the azirines rearrange smoothly to the corresponding indoles. The overall transformation offers a versatile route to indoles, complementary to the Fischer indole synthesis.
متن کاملNew synthetic route to substituted dihydroazulene photoswitches.
A new procedure for functionalization of the dihydroazulene photoswitch on its seven-membered ring was developed, which has allowed isolation of the first dihydroazulene with a phenyl substituent at position 5 from a mixture of regioisomers. Light-induced ring-opening to the corresponding vinylheptafulvene and the thermal back-reaction was studied in detail.
