Tetrahydropyranyl Ether (THPE) formation in hydroxyl group protection and conversion to other useful functionalities
RSC Adv., 2014Co-Authors: Brijesh Kumar, Mushtaq A. Aga, Abdul Rouf, Bhahwal Ali Shah, Subhash C. TanejaAbstract:This short review highlights the various methods of formation of Tetrahydropyranyl Ethers (THPEs) as a method for the protection of simple alcohols as well as a diverse range of complex molecules using a variety of reagents and reaction conditions, i.e., acid catalyst, heterogeneous catalyst and neutral reagent mediated reactions. We also discuss their direct conversion to other useful functionalities.

allyl Tetrahydropyranyl Ether a versatile alcohol thiol protecting reagent
Tetrahedron Letters, 2009Co-Authors: Brijesh Kumar, Mushtaq A. Aga, Debaraj Mukherjee, Swapandeep Singh Chimni, Subhash C. TanejaAbstract:Abstract Allyl Tetrahydropyranyl Ether (ATHPE) can be used as a versatile protecting reagent. In combination with NBS/I 2 , O -allyl group can easily be replaced by hydroxyls (including tertiary-OH) or thiols, in the molecules comprising other reactive functional groups such as halogen, nitro, acetonide and alkene under mild reaction conditions (near neutral pH and ambient temperature).

The synthesis of mono- and bicyclic Ethers via acid catalysed ring-opening cyclisation of Tetrahydropyranyl Ether derivatives
Journal of the Chemical Society Perkin Transactions 1, 2000Co-Authors: Darren J. Dixon, Steven V. Ley, Edward W. TateAbstract:A range of monocyclic and bicyclic alkenols were synthesised via acid catalysed ring-opening cyclisation of homoallylic Tetrahydropyranyl Ether derivatives in excellent yield. Upon palladium catalysed hydrogenation these products were reduced with excellent diastereoselectivity to the corresponding saturated cyclic alcohols in essentially quantitative yield.
