The present invention relates to a compound according to formula (I), (I) and pharmaceutically acceptable salts, hydrates, or solvates thereof. The invention further relates to said compounds for use in therapy, to pharmaceutical compositions comprising said compounds, to methods of treating diseases, e.g. dermal diseases, with said compounds, and to the use of said compounds in the manufacture of medicaments.
We describe here the design and development of an organocatalyticPrinscyclization. In the presence of a confined chiral imidodiphosphoric acid catalyst, salicylaldehydes react with 3‐methyl‐3‐buten‐1‐ol to afford highly functionalized 4‐methylenetetrahydropyrans in excellent regio‐ and enantioselectivity. The extreme steric demand of the acid catalyst is key for the success of this transformation

The present invention includes a process for enantioselective preparation of a non-racemic compound, which is either usable as a fragrance or flavor component or is convertible to a fragrance or flavor component by one or more additional reaction steps. The process includes the step of contacting either a substrate capable of forming a non-racemic compound by an enantioselective reaction and a co-reactant in the presence of a non-racemic catalyst, or a non-racemic or enantiopure substrate and a co-reactant, optionally in the presence of a racemic or non-racemic catalyst. The contacting is carried out at a temperature and length of time that is sufficient to produce the non-racemic compound with high optical purity. The process is used in stereoselective preparation of enantiomerically enriched intermediates useful in the preparation of non-racemic, chiral flavor and fragrance components.
