The present invention relates to a novel trisubstituted cyclic thickener or gelator. The present invention further relates to a method for thickening or gelating a solution comprising the use of such a gelator or thickener. A gelator or thickener according to the invention may for instance be used for pharmaceutical or cosmetic purposes. It may further be used as a support material in chromatographic materials or catalytically active materials.
The invention relates to a novel class of gelling agents, to a process of preparing said agents, to the use of said agents to prepare gels, and to the gels thus obtained. A gelling agent or thickener according to the invention comprises a rigid core which is functionalized with three amino acid ester or amide groups by means of an amide or urea linkage. It may be used to gelate or thicken numerous solvents.
The present invention relates to a method for producing particles of a compound of interest. In a method according to the invention a solution is provided of the compound of interest in a solvent. This solution is thickened or gelled and particles are formed. The invention further relates to a particle that is obtainable by the invention.

A study was carried out of the intramolecular cyclization of trans-1-methoxy-methyl-2-(1-hydroxyalkyl)cyclohexanes and trans-1-methoxymethyl-2-(2-hydroxy-alkyl) cyclohexanes by the action of acid chlorides of phosphorous, sulfurous and p-toluenesulfonic acids with the formation of 1-substituted trans-2-oxa-hydrindanes in low yields and 3-substituted trans-2-oxadecalins in high yields. A relationship has been established between the yields of the cyclization products and the nature of the halogenating agent. The cyclization does not proceed via an intermediate oxonium ion, but by means of an intermolecular electronic transition.
