Total synthesis of 26-fluoro-epothilone B
Koch, Guido,Loiseleur, Olivier,Altmann, Karl-Heinz
, p. 693 - 697 (2004)
An efficient synthesis of the epothilone B derivative 26-fluoroepothilone B (1) was realized by early introduction of the synthetically demanding fluoromethyl epoxide function. The presence of a fluoro substituent results in a remarkable increase in the stability of the epoxide, which tolerates the wide range of reaction conditions required for the fragment coupling step and end game transformations.
Manganese(III)-based oxidative freeradical reaction of α-allyl-β-keto ester with molecular oxygen
Ohshima, Takashi,Sodeoka, Mikiko,Shibasaki, Masakatsu
, p. 8509 - 8512 (1993)
Oxidative reactions of α-allyl-β-keto esters 5 with Mn(OAc)3·2H2O give the δ-hydroxy-β-,γ-unsaturated-α-keto esters 6 in good yields. The mechanism of this reaction is discussed.

Sudhakar, Gangarajula,Reddy, Karla Janardhan,Nanubolu, Jagadeesh Babu
, p. 2419 - 2429 (2013/03/14)
Stereoselective total synthesis of palmyrolide A, a 15-membered neuroactive macrolide, was described by adopting a synthetic strategy developed for the proposed structures, and its 5,7-epi isomers. The strategy was designed in such a way that the set of s
Triflic acid catalyzed reductive coupling reactions of carbonyl compounds with O-, S-, and N-nucleophiles
Gellert, Beate A.,Kahlcke, Nils,Feurer, Markus,Roth, Stefanie
supporting information; experimental part, p. 12203 - 12209 (2011/11/07)
Highly efficient metal-free reductive coupling reactions of aldehydes and ketones with a range of nucleophiles in the presence of triflic acid (1-5 mol %) as the catalyst are presented. The reactions can be performed at ambient temperature without exclusion of moisture or air. A range of symmetrical and unsymmetrical ethers were obtained by this method in high yields and short reaction times. For the first time, the influence of additional functionalization has been studied. Furthermore, the formation of thioethers from ketones (by addition of unmodified thiols) and of sulfonamides from either aldehydes or ketones has been achieved under catalytic conditions.
