The present invention relates to compounds of formula (I) wherein R1 to R8 and n are as defined in the description and claims, and pharmaceutically acceptable salts and esters thereof. The compounds are useful for the treatment of diseases such as diabetes.
Intramolecular Diels–Alderreactions of dioxanone-fused (Z,Z)-dienes, available in a stereoselective manner from the corresponding alcohols are described. These dienes exhibited high reactivity and high levels of endo selectivity, giving functionalized trans-fused bicyclic compounds.
The synthesis of six-, seven- and eight-membered 3-oxo oxacycloalkenes by using ring-closing metathesis has been achieved from 1-(omega-alkenyloxy)-but-3-en-2-ones. (C) 2002 Elsevier Science Ltd. All rights reserved.
Synthesis of 3-oxooxa- and 3-oxoazacycloalk-4-enes by ring-closing metathesis. Application to the synthesis of an inhibitor of cathepsin K
3-Oxooxa- and 3-oxoazacycloalk-4-enes were obtained with good yield from 1-(omega-alkenyloxy)- and 1-(omega-alkenylamino)-but-3-en-2-ones by using a ring-closing metathesis. This methodology has been used to synthesize an inhibitor of cathepsin K. (C) 2007 Elsevier Ltd. All rights reserved.
