Tetrabutylammonium fluoride: A powerful catalyst for the regioselective opening of epoxides with thiols
Albanese,Landini,Penso
, p. 34 - 36 (2007/10/02)
Tetrabutylammonium fluoride (1) catalyses under mild conditions the opening of epoxides 2a-k with thiols 3-6 to produce the corresponding β-hydroxy thioethers 7-11 in excellent yields (88-100%) and with high regioselectivity. Furthermore, O-protected glyc

, p. 2536 - 2542 (2007/10/02)
A new regioselective addition reaction of oxiranes 15-17 with active esters 18 and 19 was carried out to give the adducts 20a-f using quaternary onium salts on cross-linked polystyrene beads.The catalytic activity of the polystyrene beads was evalulated f
Regioselective Reaction of Oxiranes with S-Phenyl Thioesters Catalyzed by Quaternary Onium Salts or Crown Ether-Metal Salt Complexes
Iizawa, Takashi,Goto, Akira,Nishikubo, Tadatomi
, p. 597 - 598 (2007/10/02)
Regioselective addition reactions of 2-substituted oxiranes with S-phenyl thioesters gave 2-aceyloxy-1-phenylthio derivatives in high yield using some 18-crown-6-metal complexes as well as tetrabutylammonium salts as a catalyst under relatively mild condi
