Abstract:
The present invention provides a selective suppressor of the IgE production comprising a compound which suppresses the IgE production in a process from a differentiation of a mature B cell into an antibody-producing cell to the production of an antibody and which does not suppress or weakly suppresses the production of IgG, IgM and/or IgA which are produced at the same time, a compound of the formula (I): wherein R1–R13 are hydrogen, halogen, lower alkyl, lower alkoxy or the like, X is —O—, CH2—, —NR14— or —S(O)p— and Y is lower alkyl, lower alkenyl or the like, a process for producing the same and a pharmaceutical composition comprising the same.
Abstract:
A novel, convenient and efficient method for trifluoromethylation of substrate compounds is disclosed. Particularly, alkoxide and hydroxide induced nucleophilic trifluoromethylation of carbonyl compounds, disulfides and other electrophiles, using phenyl trifluoromethyl sulfone PhSO2CF3 (or sulfoxide PhSOCF3) is disclosed. A method of both symmetrical and unsymmetrical anti-2,2-difluoropropan-1,3-diols with high diastereoselectivity (up to 94% de) is disclosed using difluoromethyl phenyl sulfone. This unusual type of high diastereoselectivity was obtained via an intramolecular charge-charge repulsion effect rather than the traditional steric control (based on the Cram's rule). Thus, difluoromethyl phenyl sulfone can be used as a novel difluoromethylene dianion species (“−CF2−”), which can couple two electrophiles (such as diphenyl disulfide or non-enolizable aldehydes) to give new difluoromethylenated products.
