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.Application: 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 â· bf3). In a new synthesis of the abcd ring system of camptothecinapplication: 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.Ridadr: un 3267 8 / pgiiwgk germany: 2flash point(f): 240.8 Fflash point(c): 116 cr codes: 22-34-52/53s codes: 26-36/37/39-45-61iod codes: csymbol: ghs05, ghs06signal word: dangerhazard statements: h290-h301-h314-h412precautionary statements: p273-p280-p301 p310-p305 p351 p338-p310
