1. Daga cyclopentanone da n-valeraldehyde a matsayin kayan da aka samar, amyl cyclopentanone yana samuwa ne ta hanyar daskararren aldol da bushewar jiki, sannan ana yin hydrogenation na catalytic don samar da amyl cyclopentanone. Amyl cyclopentanone yana da ƙamshi mai ƙarfi na fure da 'ya'yan itace da ɗanɗanon jasmine, kuma ana iya amfani da shi a cikin dabarar dandanon sinadarai na yau da kullun, yawan shansa na iya zama ƙasa da 20%. IFRA ba ta da wani ƙuntatawa.
2. Ana shirya Hexylcyclopentanone daga n-hexylaldehyde da cyclopentanone ta hanyar daskarewa sannan kuma a yi amfani da sinadarin hydrogenation na zaɓi. Hexylcyclopentanone yana da ƙamshi mai ƙarfi na jasmine kuma yana tare da ƙamshin 'ya'yan itace, kuma ana iya amfani da shi a cikin turare da sauran sinadaran dandano na yau da kullun tare da kashi 5%. IFRA ba ta da wani ƙuntatawa.
3. 1-pentene ko 1-heptene da aka samu ta hanyar fashewar paraffin ko kuma bushewar barasa mai dacewa a matsayin kayan masarufi, a gaban di-tert-butyl peroxide a matsayin mai farawa, amsawar ƙarin rukuni kyauta tare da cyclopentanone don samar da 2-amyl cyclopentanone (ko 2-heptyl cyclopentanone), bayan oxidation ya zama delta-decalactone (ko delta-dodecalactone).
4. Hanyar hadawa da cyclopentanone a matsayin kayan farawa tana da mafi girman darajar samar da masana'antu. Da farko ana haɗa Cyclopentanone da n-valeraldehyde, kuma sakamakon Chemicalbook ana cire shi daga jiki sannan a yi amfani da hydrogen don samar da 2-amylcyclopentanone, sannan a ƙarshe a samar da delta-decalactone ta hanyar ƙara girman zoben oxidative.
5.delta-decanolactone galibi ana amfani da shi a cikin hadaddiyar dandanon abinci, inda ake kyautata zaton yana da dandanon kirim na halitta. Kafin wannan, na dogon lokaci, masu turare suna iyakance ne kawai ga amfani da kayan ƙanshi na monomer kamar butanedione da vanillin a matsayin babban kayan da ake amfani da su wajen shirya dandanon kirim. Duk da haka, mutane gabaɗaya suna jin cewa ɗanɗanon kirim ɗin da aka haɗa ya yi ƙasa da samfurin halitta dangane da ɗanɗano ko ɗanɗano. Sai bayan amfani da delta-decalactone ne kawai, za a iya samun ɗanɗanon kirim na gaske, musamman haɗin delta-decalatone da delta-dodecalactone a matsayin babban kayan ƙanshi, ɗanɗanon kirim ɗin da aka shirya ya fi kyau.
6. Amfani da cyclopentanone da valeraldehyde a matsayin kayan da aka samar, ana iya samar da 2-(1-hydroxyl) amyl cyclopentanone, ana iya yin maganin dimethyl malonate, sannan a yi hydrolysis a 160 ~ 180℃, ana iya shirya decarboxylated, esterification, dihydrojasmonate methyl ester. Ana iya shirya Methyl jasmonate dihydrojasmonate ɗanɗano ne na ɗan lokaci wanda GB2760-1996 ya yarda da shi a ƙasarmu. Ƙanshinsa ya fi na halitta methyl jasmonate kyau, kuma halayensa suna da ƙarfi.
