Two approaches to optically active 2-substituted chromans and chrornan-4-ones are described. The first utilized an intermolecular Mitsunobu reaction of a homochiral halopropanol and 2-bromophenol followed by cyclization to the 2-substituted chroman. In addition, a double lithiation procedure was developed to introduce additional functionality to the chroman. The second approach utilized an intramolecular Mitsunobu cyclization to give the 2-substituted chroman-4-one nucleus. The methodologies were applied to the syntheses of several biologically active natural and synthetic products. (c) 2005 Elsevier Ltd. All rights reserved.
Aryl(sulfonyl)amino Group: A Convenient and Stable Yet Activated Modification of Amino Group for Its Intramolecular Displacement
Aryl(sulfonyl)amino groups, readily derived from sulfonyl- or arylamines by standard methods as well as the recently introduced methods of sulfonylation and arylation, proved to be good leaving groups in intramolecular substitution reactions by various nitrogen, oxygen, and carbon nucleophiles.

The present invention aims to provide a pharmaceutical agent for the prophylaxis and/or treatment of Alzheimer's disease, which has a novel action mechanism and shows less side effects. A polyphenol derivative having liposolubility enhanced by the introduction of at least one kind of a liposoluble group selected from the group consisting of a chain saturated hydrocarbon group, a chain unsaturated hydrocarbon group, a cyclic saturated hydrocarbon group, a cyclic unsaturated hydrocarbon group, an aromatic hydrocarbon group, a liposoluble vitamin residue and a sterol residue has an action to potentiate neprilysin activity, and is useful as a pharmaceutical agent for the prophylaxis and/or treatment of Alzheimer's disease.
