Hoʻolauna

ʻO Z-Tetrahydro-6-(2-pentenyl)-2H-pyrano-2-one kahi mea hoʻohuihui me nā waiwai penei:

 

ʻO ke ʻano: ʻeleʻele a i ʻole melemele paʻa;

 

ʻO nā hoʻohana nui o Z-tetrahydro-6-(2-pentenyl)-2H-pyrano-2-one penei:

 

Nā mea hoʻohālikelike: ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik, hiki ke hoʻohana ʻia e synthesize i nā pūhui organik ʻē aʻe;

 

ʻO ke ʻano no ka hoʻomākaukau ʻana o Z-tetrahydro-6-(2-pentenyl)-2H-pyrano-2-one hiki ke hana ʻia e nā pae aʻe:

 

2-pentenylpyran ua oxidized me ka oxidant e loaa ketone alani pentene.

Ua hoʻokō ʻia ka hopena hoʻohui ma waena o ketone alani pentene a me ka sodium borate e hana i ʻelua stereoisomers: Z-tetrahydro-6-(2-pentenyl) -2H-pyran-2-one a me E-tetrahydro-6-(2-pentenyl) - 2H-pyrano-2-hoʻokahi;

Ua hoʻokaʻawale ʻia nā isomers no ka loaʻa ʻana o ka Z-tetrahydro-6-(2-pentenyl) -2H-pyran-2-one i makemake ʻia.

 

ʻIke palekana: Pono ka loiloi palekana kūikawā o Z-tetrahydro-6-(2-pentenyl)-2H-pyrano-2-one i ka ʻikepili palekana kemika pili. Ma keʻano laulā, pono e mālama pono ʻia, mālama ʻia a hoʻohana ʻia nā kemika, me ka mālama ʻana e pale aku i ka pili ʻana me ka ʻili, nā maka, a me ka ʻōpū hanu. E hoʻohana i nā mea pale i ka wā e hoʻohana ai e pale aku i ka hanu ʻana i ka mahu a i ʻole ka lepo.
