Copper catalyzed allylic oxidation with peresters

<b>Synthesis of 7-dehydrocholesterol through hexacarbonyl molybdenum catalyzed elimination reaction</b>

“…Choleterol-3,7-diacetate formation is also reported by using electrochemical oxidation of cholesterol [12]. Karash [13,14] procedure of allylic esterification using copper catalyst has taken much more attention throughout the history for the synthesis of allylic acetates. Different experimental conditions are optimized to make the reaction simple and productive.…”

New chiral bidentate ligands containing thiazolyl and pyridyl donors for copper-catalyzed asymmetric allylic oxidation of cyclohexene

“…The first asymmetric version of the Kharash-Sosnovsky reaction was reported in 1965 by Denney et al [8], though the enantioselectivity was not very good. Better enantioselectivity control has started to appear recently [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Among them, some of them are of non C 2 -symmetry [18,25,26].…”

Synthesis of two new chiral fluorous bis(oxazolines) and their applications as ligands in catalytic asymmetric reactions

“…[1][2][3][4][5][6][7] The broad range of applications of these chiral ligands and the very high enantioselectivities obtained have stimulated an intense research activity concerning their immobilization on supports in order to recover and recycle the chiral catalyst. 8 This heterogenization has been performed using bonding to solid inorganic [9][10][11][12][13][14][15] or organic supports, 16,17 as well as to soluble organic polymers.…”
