DICHLORO-BIS(TRIFLUOROMETHANESULFONATO)TITANIUM(IV) AS AN EFFECTIVE PROMOTER IN THE CLAISEN ESTER CONDENSATION
Tanabe, Yoo,Mukaiyama, Teruaki
, p. 1867 - 1870 (1984)
Inter- and intra-molecular condensation (the Claisen and the Dieckmann condensations) between ester functions have been effected by the combined use of dichloro-bis(trifluoromethanesulfonato)titanium(IV) and tertiary amine under mild conditions.
THE SELECTIVE CLAISEN AND DIECKMANN ESTER CONDENSATION PROMOTED BY DICHLOROBIS(TRIFLUOROMETHANESULFONATO)TITANIUM(IV)
Tanabe, Yoo
, p. 1917 - 1924 (2007/10/02)
Inter and intramolecular condensations (the Claisen and the Dieckmann condensations) between ester functions have been performed by the combined use of dichlorobis(trifluoromethanesulfonato)titanium(IV) (=dichlorobis(triflato)titanium(IV)) and tertiary amine under mild reaction conditions.These results led to the development of the selective (crossed) Claisen and Dieckmann ester condensation between methoxymethyl ester and methyl ester, in that, dichlorobis(triflato)titanum(IV) contribute to control the direction of the reaction.
