Sm. Ma et Lm. Venanzi, THE EFFICIENT DEPROTECTION OF ACETALS AND TETRAHYDROPYRANYL DERIVATIVES OF PHENOLS USING [RU(CH3CN)(3)(TRIPHOS)](OTF)(2) AS A CATALYST, Tetrahedron letters, 34(50), 1993, pp. 8071-8074
Acetals and tetrahydropyranyl derivatives of phenols are efficiently a
nd highly chemoselectively deprotected in the presence of catalytic am
ounts of [Ru(CH3CN)(3)(triphos)]-(OTf)(2) (triphos = CH3C(CH(2)PPh(2))
(3)), under mild condition, in good to excellent yields.
