1,8-Diazabicyclo[5.4.0]undec-7-ene is a bicyclic amidine base. It is non-nucleophilic, sterically hindered, tertiary amine base in organic chemistry. It is reported to be superior to amine catalyst in Baylis-Hillman reaction. It promotes the methylation reaction of phenols, indoles and benzimidazoles with dimethyl carbonate under mild conditions.

Application

Used in a new synthesis of the ABCD ring system of Camptothecin.

1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) may be used:

• as catalyst for carboxylic acid esterification with dimethyl carbonate
• in the synthesis of duocarmycin and CC-1065 analogs
• as catalyst in aza-Michael addition and Knovenegal condensation reaction
• as base for dehalogenation of halogenated Diels-Alder adducts and the resulting activated 2,4-dienones were subjected to regio- and stereo-directed Michael additions, using Yamamoto′s reagent (CH₃Cu · BF₃)
• in a new synthesis of the ABCD ring system of Camptothecin

1,8-Diazabicyclo[5.4.0]undec-7-ene may be used as an catalyst for the dissolution and activation of cellulose by a reversible reaction of its hydroxyl groups with carbon dioxide. This dissolved cellulose system can be derivatized to form cellulose mixed esters.

For the production of cephalosporins semi-synthetic antibiotics. Used as a resin curing accelerator (especially for exterior packaging resins for integrated circuits and electronic components)
