experimental part, p. 3369 - 3377 (2011/03/19)
The ion-exchange resin Dowex 50WX4-100 has been found to catalyze efficiently the protection reaction of a variety of alcohols with 2,3-dihydro-4H pyran (DHP) and dichloromethane at ambient conditions. Copyright Taylor & Francis Group, LLC.
Zeolite-catalyzed environmentally friendly tetrahydropyranylation of alcohols and phenols
Hegedues, Adrienn,Vigh, Ilona,Hell, Zoltan
, p. 4145 - 4152 (2007/10/03)
A simple and environmentally friendly tetrahydropyranylation of various alcohols and phenols at room temperature was elaborated by using a small pore size zeolite. The material is also suitable for the deprotection but with less efficiency.
