一般說明

Phase-transfer benzylation reaction of ethyl 2-oxocyclopentanecarboxylate with benzyl bromide has been investigated in microreactor. Ethyl 2-oxocyclopentanecarboxylate participates in cobalt(II) Schiff′s base complex catalyzed oxidation of primary and secondary alcohols to aldehydes and ketones.

應用

Ethyl 2-oxocyclopentanecarboxylate was used in stereoselective synthesis of (±)-cis,cis-spiro[4.4]nonane-1,6-diol. It was also used in synthesis of tanikolide.
