Synthesis of allene triazole through iron catalyzed regioselective addition to propargyl alcohols.
Allene triazole derivatives were successfully synthesized for the first time through iron catalyzed regioselective triazole addition to tertiary propargyl alcohols. The reaction proceeds under mild conditions, giving the desired allene-triazoles in good to excellent yields (up to 96%). The resulting allene-triazoles were confirmed by X-ray crystallography and indicated improved stability.
متن کاملIron-catalyzed ene-type propargylation of diarylethylenes with propargyl alcohols.
The diarylalkenyl propargylic complex framework has been found in many natural products and medicinal regents. Herein, we have disclosed an unprecedented FeCl(3) catalyzed ene-type reaction of propargylic alcohols with 1,1-diaryl alkenes which enabled us to furnish a diarylalkenyl propargylic complex framework in moderate to high chemical yields (up to 98%).
متن کاملRhenium-catalyzed coupling of propargyl alcohols and allyl silanes.
A mild method for the regioselective coupling of propargyl alcohols and allylsilanes is described. The method employs an air- and moisture-tolerant rhenium-oxo complex ((dppm)ReOCl3) as a catalyst for the formation of sp3-carbon-sp3-carbon bonds without the need for prior activation of the propargyl alcohol as a halide or pseudohalide. The stability of the high oxidation state rhenium complex a...
متن کاملRegioselective N-alkylation of 2-aminobenzothiazoles with benzylic alcohols.
The preparation of 2-(N-alkylamino)benzothiazoles via regioselecive N-alkylation of 2-aminobenzothiazoles has been accomplished by using benzylic alcohols as alkylating agents.
متن کاملExpedient synthesis of new cinnoline diones by Ru-catalyzed regioselective unexpected deoxygenation-oxidative annulation of propargyl alcohols with phthalazinones and pyridazinones.
Ruthenium-catalyzed simple, cascade and one-pot synthesis of cinnoline-fused diones has been carried out by the C-H activation of phthalazinones/pyridazinones accomplished by the unusual deoxygenation of propargyl alcohols. The bond selectivity is accredited to the traceless directing nature of the hydroxyl group of propargyl alcohol. A sequential C-H activation, insertion and deoxy-oxidative a...
