4-Hydroxyphenylboronic acid pinacol ester, e taʻua foi o le HBP ester, o se vailaʻau vailaʻau e maua ai faʻaoga i vaega eseese ona o ona uiga faʻapitoa e pei o se ester boronic.O lona fausaga vailaʻau e aofia ai se boron atom e faʻapipiʻi i se vaega phenolic e ala i se fesoʻotaʻiga ester, ua avea ai ma poloka fale taua mo le faʻaogaina o meaola. -ga fa'atasi.O lenei tali e aofia ai le fausia o se fusi carbon-carbon i le va o le aryl poʻo le vinyl boronic acid ma le aryl poʻo le vinyl halide poʻo le triflate.I le avea ai o se ester boronic, o le HBP ester e galue e avea o se mea muamua i le boronic acid tutusa, lea e mafai ona oʻo i le faʻaogaina o fesoʻotaʻiga faʻatasi ma electrophiles eseese, e taʻitaʻia ai le faʻavaeina o molelaʻau faʻapitoa.O lenei tali e iai sona aoga taua i vailaʻau kemisi, agrochemical synthesis, material science, ma le tele o isi vaega o organic synthesis. O le faʻaogaina o le HBP ester o loʻo taoto i lona gafatia e faʻaogaina suiga faʻavae, e pei o le faʻamaʻiina poʻo le faʻaitiitia, e faʻafeiloaʻi ai galuega faʻaopoopo i totonu o le. mole mole.Mo se faʻataʻitaʻiga, o le vaega hydroxyl o le phenolic moiety e mafai ona puipuia ma mulimuli ane faʻateʻaina, faʻatagaina mo suiga filifilia ma le faʻavasegaina o le faʻalapotopotoga.O lenei meatotino e avea ai le HBP ester o se meafaigaluega taua i le tuʻufaʻatasia o vailaʻau, agrochemicals, ma isi vailaʻau lelei. E le gata i lea, o le HBP ester e masani ona faʻaaogaina i le fausiaina o masini mole mole ma suʻega.Ona o le boron atom i lona fausaga, e mafai ona fausia faʻalavelave faʻalavelave faʻatasi ma diols poʻo polyols, e pei o suka poʻo gaʻo.O lenei meatotino e mafai ai ona fausia ni masini e fa'atatau i le boronate mo le su'esu'eina o le kulukose, fa'apea fo'i ma isi molela'au talafeagai.O le HBP ester e mafai ona tuʻufaʻatasia i faʻasalalauga faʻapitoa eseese, e aofia ai suʻesuʻega faʻafefete poʻo lanu, e maua ai se auala e iloa ai suʻesuʻega faʻapitoa i meaola poʻo faʻataʻitaʻiga o le siosiomaga. mo lona sao taua i faiga fa'afuala'au.O le boron atom e mafai ona auai i fegalegaleaiga ma biomolecules, e pei o nucleic acids poʻo polotini, ma ua suʻesuʻeina mo le tuʻuina atu o vailaʻau faʻapitoa, faʻaleleia le faʻaogaina o le telefoni feaveaʻi, poʻo le faʻasaʻoina o le tuʻuina atu o vailaʻau faʻamaʻi. fa'aaogaina i le fa'aogaina o meaola, fa'alogoina o fa'aoga, ma faiga e tu'uina atu ai vaila'au.O lona aoga ester boronic e mafai ai ona auai i le Suzuki-Miyaura cross-coupling reaction ma faia suiga vaega galue, faalauteleina lona aoga synthetic.E le gata i lea, e mafai e le HBP ester ona fausia faʻalavelave faʻalavelave faʻatasi ma diols, e taua tele mo le atinaʻeina o masini mole.O lona gafatia i faiga e tu'uina atu ai vaila'au o lo'o fa'amanino atili ai lona taua o se tu'ufa'atasiga tele i matā'upu fa'asaienisi ma fa'atekonolosi eseese.
