Ts'ebeliso:Di-Tit-ityl dicarbonate (Boc2o) e sebelisoa haholo bakeng sa ho hlahisa lihlopha tse sirelelitsoeng ka pekello ea pepeneneng. E bapala karolo ea bohlokoa ho lokiseng ea 6-acetyl-1,2,3,4-tetrahydropyridinedy ka ho araba ka 2-Piperdionene. E sebetsa e le sehlopha se sirelletsang se sebelisitsoeng ka thata ea pepnthesis e tiileng.
Kenyelletso e qaqhileng
Di-Tort-butyl dicarbonateke ntho e khothalletsoang e sebelisitsoeng ho li-syntmosis tse manyolo. E boetse e tsejoa e le oa T-Boc anhydride kapa Boc anhydride. E tloaelehile ho sireletsa lihlopha tsa pono nakong ea karabelo ea lik'hemik'hale. Di-Tit-ityl Dicarbonate o fantisi e nang le Icenes ho folisa litlolo tsa Karbamate, o fana ka tšireletso ea nakoana bakeng sa sehlopha sa apane. Hang ha karabelo e lakatsehang e phethehile, sehlopha sa carbamate se ka tlosoa habonolo ke kalafo ka acid, ea inehelang ts'ebetso ea mantlha ea tlhaho. Leeba la bohlokoa bakeng sa ho fetola lihlopha tse itseng tse sebetsang ka nepo ho limolek'hule tsa manyolo.

Tšireletso ea Lihlopha tsa Hydroyl:Dicarbonate ea Di-Finel a ka etsa lintho tse ngata ho theha lijana, li sirelletsa sehlopha sa hydroyl. Sehlopha sa carbonate se ka tlosoa ka mor'a maemo a nepahetseng, a lumella ho fetolela ka khetho ea lihlopha tse ling tse sebetsang.
Boitšoaro ba ho senya boaparo:Dicarbonate ea di-Fiat-butyl e ka sebelisoa e le mohloli oa khabone ea khabone ka mokhoa oa ho fana ka carbony. E sebetsana le li-nucleophoges tse kang isiun, linoko le lithiol ho etsa lihlahisoa tsa carbonylated.
Litokisetso tsa li-acid acid.Ho arabela dicrarbonate le thionyl chloride kapa oxalyl chlonide e fana ka li fana ka li-changkide tse tsamaellanang tsa acid. Acid clorides a acid ke rekhoes tse ngata tse fapaneng tse sebelisoang litlhare tsa mefuta-futa tsa maiketsetso.
