The present invention relates to compounds with the formulas (I), (II), and (III), or a pharmaceutically acceptable salt thereof: wherein T is a (4 to 10)-membered heterocyclyl selected from the group consisting of and wherein R1. R2 and R3 are as defined in the specification. The invention also relates to pharmaceutical compositions comprising the compounds of formulas (I), (II), and (III) and methods of treating a condition that is mediated by the modulation of the 11-β-hsd-1 enzyme, the method comprising administering to a mammal an effective amount of a compound of formulas (I), (II), and (III).

The direct amidation of aminoacidderivatives catalyzed by arylboronic acids has been examined. The reaction was generally slow relative to simple amine-carboxylic acid combinations though proceeded at 65–68 °C generally avoiding racemization. 3,4,5-Trifluorophenylboronic and o-nitrophenylboronic acids were found to be the best catalysts, though for slower dipeptide formations, high catalyst loadings

日期:2012.2.6
Metal‐free catalysis: A method for the transamidation of primaryamides with primary or secondary amines provides access to secondary and tertiary amides, by utilizing catalytic quantities of hydroxylaminehydrochloride to activate the chemically robust primary amide group (see scheme). A mechanism of primary amide activation through a hydrogen‐bonding complex is proposed.
