4-Hydroxyphenylboronic acid pinacol ester, nke a makwaara dị ka HBP ester, bụ ihe mejupụtara kemịkalụ nke na-achọta ngwa n'akụkụ dị iche iche n'ihi ihe pụrụ iche ya dị ka ester boronic.Ọdịdị kemịkal ya nwere boron atom nke etinyere na otu phenolic site na njikọ ester, na-eme ka ọ bụrụ ngọngọ ụlọ bara uru maka njikọ organic.Na njikọ organic, 4-Hydroxyphenylboronic acid pinacol ester na-ejikarị eme ihe dị ka reagent maka obe Suzuki-Miyaura. - njikọ mmeghachi omume.Mmeghachi omume a na-agụnye nhazi nke njikọ carbon-carbon n'etiti aryl ma ọ bụ vinyl boronic acid na aryl ma ọ bụ vinyl halide ma ọ bụ triflate.Dị ka ester boronic, HBP ester na-arụ ọrụ dị ka ihe mmalite nke boronic acid kwekọrọ, nke nwere ike ịnweta mmeghachi omume njikọ na electrophiles dị iche iche, na-eduga n'ịmepụta ihe ndị dị mgbagwoju anya.Nke a mmeghachi omume nwere ịrịba ngwa na ọgwụ kemịkalụ, agrochemical njikọ, ihe sayensị, ihe onwunwe sayensị, na ọtụtụ ndị ọzọ ebe nke organic synthesis.The versatility nke HBP ester dabeere na ya ike ime ọtọ otu mgbanwe, dị ka ọxịdashọn ma ọ bụ mbelata, iwebata ọzọ ọrụ n'ime molekul.Dịka ọmụmaatụ, enwere ike ichebe ìgwè hydroxyl nke phenolic moiety ma mesịa mebie ya, na-enye ohere maka mgbanwe nhọrọ na mgbanwe dị iche iche nke ogige ahụ.Ihe onwunwe a na-eme ka HBP ester bụrụ ngwá ọrụ bara uru na njikọ nke ọgwụ, agrochemicals, na kemịkalụ ndị ọzọ dị mma. Ọzọkwa, a na-ejikarị HBP ester eme ihe na-emepụta ihe mmetụta molecular na nyocha.N'ihi atom nke boron na nhazi ya, ọ nwere ike ịmepụta mgbagwoju anya nwere diol ma ọ bụ polyols, dị ka sugars ma ọ bụ carbohydrates.Ihe onwunwe a na-enyere aka ịmepụta ihe mmetụta nke boronate maka ịchọpụta glucose, yana ụmụ irighiri ihe ndị ọzọ metụtara ndụ.Enwere ike itinye HBP ester n'ime usoro nyocha dị iche iche, gụnyere fluorescent ma ọ bụ nyocha colorimetric, na-enye ụzọ iji chọpụta ihe nyocha kpọmkwem na ihe atụ nke ndụ ma ọ bụ gburugburu ebe obibi. maka ọrụ nwere ike ime na usoro nnyefe ọgwụ.Atọm boron nwere ike isonye na mmekọrịta ya na biomolecules, dị ka acid nucleic ma ọ bụ protein, a nyochawokwa ya maka nnyefe ọgwụ ezubere iche, nkwalite cellular nnabata, ma ọ bụ ntọhapụ a na-achịkwa nke ndị na-ahụ maka ọgwụgwọ. eji na organic synthesis, ngwa mmetụta na usoro nnyefe ọgwụ.Ọrụ ester boronic ya na-enyere ya aka isonye na mmeghachi omume njikọta nke Suzuki-Miyaura ma mee mgbanwe otu ọrụ na-arụ ọrụ, na-agbasawanye ike ya.Na mgbakwunye, HBP ester nwere ike mepụta ogige ndị nwere ike ịtụgharị ya na diol, na-eme ka ọ baa uru maka mmepe nke sensọ molekụla.Ike ya na usoro nnyefe ọgwụ na-emesiwanye ike mkpa ọ dị dị ka ngwakọta dị iche iche na mpaghara sayensị na nkà na ụzụ dị iche iche.
