Solvent-free catalysed synthesis of tetrahydropyran odorants: The role of SiO2·p-TSA catalyst on the Prins-cyclization reaction

An efficient, green and solvent-free catalysed Prins-cyclization reaction based on the simple grinding of an aldehyde and a homoallylic alcohol in the presence of catalytic amount of p-TSA on silica gel is reported. By this protocol were synthesized tetrahydropyran odorants including commercial Florol? and Clarycet?, in one and two steps respectively.

Preparation of the Enantiomerically Enriched Isomers of the Odorous Cyclic Ethers Clarycet, Florol, and Rhubafuran by Enzymatic Catalysis

All the enantiomerically enriched stereoisomers of Clarycet (1), Florol (2), and Rhubafuran (3) were prepared by biocatalysis routes. Their absolute configurations were established, and their olfactory properties were fully evaluated.
