TETRAHYDROPYRANYL LOWER ALKYL ESTERS AND THE PRODUCTION OF SAME USING A KETENE COMPOUND

The present invention relates to tetrahydropyranyl lower akyl esters and specifically to tetrahydropyranyl acetates, a method for preparation thereof using ketene and use thereof as fragrances and aroma substances.

Sulfonated Hyper-cross-linked Porous Polyacetylene Networks as Versatile Heterogeneous Acid Catalysts

Two highly sulfonated micro/mesoporous polymers, P(1,3-DEB)-SO3H and P(1,4-DEB)-SO3H, with permanent porosity, the specific surface area about 550 m2 ? g?1 and the content of SO3H groups of 2.7 mmol ? g?1 were prepared as new acid Porous Polymer Catalysts, PPCs. The PPCs were achieved by easy sulfonation of parent hyper-cross-linked micro/mesoporous polyacetylene-type networks resulting from a chain-growth homopolymerization of 1,3- and 1,4-diethynylbenzenes. New PPCs are reported as highly active and reusable heterogeneous catalysts of esterification of fatty acids with methanol and ethanol, Prins cyclization of aldehydes with isoprenol and intramolecular Prins cyclization of citronellal to isopulegol. The catalytic activity of the micro/mesoporous PPCs (TON values up to 522 mol ? mol?1) was higher than that of commercial polymer-based heterogeneous catalyst Amberlyst 15 possessing gel texture without permanent pores and that of p-toluenesulfonic acid applied as a homogeneous catalyst.

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.

Process for producing a pyran compound

The invention relates to a process for producing a mixture of a pyran represented by the formula (II) and a hydroxypyran represented by the formula (III) by reacting aldehyde (I) with isoprenol.R1 ―CHO wherein R1 represents an alkyl or alkenyl group having 1 to 12 carbon atoms, an optionally alkyl- or alkoxy-substituted aryl group having 6 to 12 carbon atoms in total, or the like. Further, the hydroxypyran compound in the resulting mixture is subjected to dehydration reaction in the presence of an acid to produce a pyran compound represented by the formula (II).

Novel mercuric triflate-catalyzed condensation of ketones and homoallyl alcohols

Novel condensation of ketones with homoallyl alcohols catalyzed by Hg(OTf)2 has been developed, generating a 6-membered ring ether alcohol, bisether, and olefins. The reaction is initiated by hemiacetal formation, and cyclization of the resulting oxonium action provides the 6-membered ring carbocation as a common intermediate. Thus, it is a catalytic Prins-type condensation of non-activated hormoallyl alcohols and ordinary ketones.

REACTIONS ON A SURFACE. 1. CONDENSATION OF 3-METHYL-3-BUTEN-1-OL WITH CARBONYL COMPOUNDS ON SiO2 AND Al2O3

3-Methyl-3-buten-1-ol reacts with various aldehydes and ketones on silica gel and Al2O3 surfaces in the absence of solvents and conventional catalysts for this reaction to form derivatives of di- and tetrahydropyrans.
