3,4-Dihydro-2H-pyran CAS 110-87-2

ʻO 3,4-Dihydro-2H-pyran (DHP, CAS 110-87-2) he wai waihoʻoluʻu ʻole a hiki ke hoʻā ʻia me ka ʻala like ʻole etera a lilo ia ma ke ʻano he kumu waena o ka synthesis organik. Ma ke ʻano he eter heterocyclic ʻeono, ʻike ʻia ʻo DHP no kāna kuleana i ka pale ʻana i nā hana ʻona ma o ka hoʻokumu ʻana o ka ether tetrahydropyranyl (THP). He mea nui kēia i ka synthesis multi-step o nā lāʻau lapaʻau, nā huahana kūlohelohe, a me nā kemika kūikawā.

Hana ʻia ma o ka catalytic hydrogenation o dihydropyran a i ʻole biomass-furfural i loaʻa, ua kūpono ka DHP me nā pono o ke kemika hoʻomau. Kākoʻo nō hoʻi kona waiwai kumu-paʻa paʻa, ʻike ʻakika, a me ka volatility-i kona hoʻohana ʻana i nā resins, nā uhi, a me ka hana kemika maikaʻi.

(He Kūwaena Nui no ka Synthesis Kiʻekiʻe)

• ʻO ka pale ʻana i ka waiʻona i ka hoʻohuihui ʻana:

Hoʻokumu ʻo DHP i nā eter THP me nā waiʻona ma lalo o ka catalysis acid haʻahaʻa, e hoʻolilo ana i nā waiʻona i ka nucleophiles a me nā kumu i ka wā o nā kaʻina hana synthetic paʻakikī. Hoʻopau maʻalahi nā hui THP me ka hoʻohana ʻana i nā waikawa dilute.

• ʻO ka hoʻohana ʻana i nā lāʻau lapaʻau multistep:

Hoʻohana ʻia i ka synthesis o nā steroids, HIV protease inhibitors, a me macrolide antibiotics e ka koho masking hydroxyl group.

• Kūwaena i loko o nā mea hana kemika:

Precursor i ka synthesis o nā mea ʻono, nā mea ʻala (e laʻa, nā pūhui musk), a me nā mea kanu ʻai.

• Kemika Polymer a me Resin:

Hāʻawi i nā poloka kūkulu ether cyclic no nā-pena hana kiʻekiʻe a me nā ʻōnaehana hoʻōla UV-.

• Biomass-Molecule Platform Loaʻa:

Hiki ke hoʻohui ʻia ka DHP mai furfural, e lilo ia i mea koʻikoʻi i waena o ka bio-mea hoʻoheheʻe a me ka hoʻomohala hoʻohui.

Hoʻopili:
Hoʻopaʻa ʻia i loko: 180 kg pahu (ʻoihana), 1L/5L ʻōmole (lab scale)
