  • Patent number: 8524782
    Abstract: The present invention provides a scalable process for the preparation of stilbenes by (i) condensing 3,5-dialkylbenzyl phosphonates with 4?-O-tetrahydropyranyl benzaldehyde to get 3,5-alkyl-4?-O-tetrahydropyranyl Stilbene and (ii) deprotecting the obtained 3,5-Dialkyl-4?-O-tetrahydropyranylstilbene to yield stilbenes. The present invention also provides a novel intermediate 3,5-Dialkyl-4?-O-tetrahydropyranyl stilbene, which is a key intermediate for the synthesis of stilbenes such as Pterostilbene and Resveratrol. The present invention also provides characteristics of various solid forms of Pterostilbene, methods for their preparation, as well as dosage forms containing the same for administration to or consumption by humans.
