supporting information; experimental part, p. 5107 - 5124 (2011/07/31)
While developing new variations of the Prins cyclisation reaction, the effect of the choice of Lewis acid on the outcome of the reaction and the product(s) has been investigated, yielding hitherto unseen dihydropyran products in the Prins cyclisation reac
Cellulose-SO3H as a recyclable catalyst for the synthesis of tetrahydropyranols via prins cyclization
Subba Reddy,Venkateswarlu,Narayana Kumar,Vinu
experimental part, p. 6511 - 6515 (2011/02/24)
Tetrahydropyranols are prepared in good yields and with high cis-selectivity by means of the Prins cyclization using cellulose-sulfonic acid under mild reaction conditions. This is the first report on the preparation of tetrahydropyranols using epoxides and homoallylic alcohols via Prins cyclization.
The 'aqueous' Prins cyclization: A diastereoselective synthesis of 4-hydroxytetrahydropyran derivatives
Yadav, Jhillu S.,Subba Reddy, Basi V.,Narayana Kumar, Gunda G. K. S.,Aravind, Seema
, p. 395 - 400 (2008/09/20)
Phosphomolybdic acid (H3PMo12O40, a heteropoly acid) is found to catalyze efficiently the Prins cyclization of homoallylic alcohols with aldehydes in water at room temperature to provide tetrahydropyran-4-ol derivatives in high yields with all cis-selectivity. Only cyclic ketones can give spirocyclic products. The use of phosphomolybdic acid in water makes this procedure simple, more convenient, cost-effective, and environmentally friendly.
