TY - JOUR A1 - Schmidt, Bernd A1 - Nave, Stefan T1 - Stereoselective syntheses of enantiomerically pure 2,5-disubstituted dihydropyrans based on olefin metathesis JF - The journal of organic chemistry N2 - A short synthesis of 2,5-disubstituted dihydropyrans starting from D-mannitol as a chiral building block is described. Our synthetic approach combines ruthenium-catalyzed ring closing olefin metathesis and palladium-catalyzed nucleophilic substitution.

This method has significant advantages over other O-allylation methods as it provides a solution to several problems previously observed for this synthetic transformation Y1 - 2006 UR - http://onlinelibrary.wiley.com/doi/10.1002/adsc.200505361/pdf U6 - https://doi.org/10.1002/adsc.200505361 ER -
