Isingeniso

I-Z-Tetrahydro-6-(2-pentenyl)-2H-pyrano-2-one iyinhlanganisela yemvelo enezici ezilandelayo:

 

Ukubukeka: okuqinile okungenambala noma okuphaphathekile okuphuzi;

 

Ukusetshenziswa okuyinhloko kwe-Z-tetrahydro-6-(2-pentenyl)-2H-pyrano-2-one imi kanje:

 

Izimaphakathi zokusabela: njengeziphakathi ezibalulekile ekuhlanganiseni kwe-organic, zingasetshenziswa ukuhlanganisa ezinye izinhlanganisela eziphilayo;

 

Indlela yokulungiselela i-Z-tetrahydro-6-(2-pentenyl)-2H-pyrano-2-one ingenziwa ngezinyathelo ezilandelayo:

 

I-2-pentenylpyran yayifakwe i-oxidant ukuze ithole i-pentene orange ketone.

Ukusabela okungeziwe phakathi kwe-pentene orange ketone ne-sodium borate kwenziwa ukuze kwakhiwe ama-stereoisomers amabili: Z-tetrahydro-6-(2-pentenyl)-2H-pyran-2-one kanye ne-E-tetrahydro-6-(2-pentenyl)- I-2H-pyrano-2-eyodwa;

Ama-isomer ahlukaniswa ukuze athole i-Z-tetrahydro-6-(2-pentenyl) efunwayo -2H-pyran-2-one.

 

Ulwazi lokuphepha: Ukuhlolwa okuqondile kokuphepha kwe-Z-tetrahydro-6-(2-pentenyl)-2H-pyrano-2-one kudinga ukubhekisela kudatha yokuphepha kwamakhemikhali efanele. Ngokuvamile, amakhemikhali adinga ukugcinwa ngendlela efanele, asingathwe, futhi asetshenziswe, ngezinyathelo zokuphepha ukuze agweme ukuthintana nesikhumba, amehlo, nemigudu yokuphefumula. Gqoka okokuvikela ngesikhathi sokusetshenziswa ukuze ugweme ukuhogela inkungu noma uthuli.
