The Liver X Receptor (LXR) alpha and beta isoforms are members of the type II nuclear receptor family which function as a heterodimer with the Retinoid X Receptor (RXR). Upon agonist binding, the formation of the LXR/RXR heterodimer takes place and ultimately the regulation of a number of genes begins. The LXR isoforms share 77% sequence homology, with(More)
The Liver X Receptor (LXR) alpha and beta isoforms are members of the type II nuclear receptor family which function as obligate heterodimers with the Retinoid X Receptor (RXR). Upon agonist binding, the DNA Binding Domain (DBD) of LXR interacts with LXR response elements on target genes to initiate transcription. A number of genes have been shown to be(More)
A highly chemo- and diastereoselective protocol toward amino-substituted donor-acceptor cyclopropanes via the formal nucleophilic displacement in bromocyclopropanes is described. A wide range of N-nucleophiles, including carboxamides, sulfonamides, azoles, and anilines, can be efficiently employed in this transformation, providing expeditious access to(More)
An expeditious and cost-efficient method for synthesis of 1-arylcycloprop-2-ene-1-carboxamides was developed. This one-pot protocol involving coupling of amines with acyl chlorides, generated upon treatment of cyclopenylcarboxylic acids with oxalyl chloride, is applicable for the preparation of sensitive products with a reactive, unsubstituted strained(More)
Densely substituted cyclopropanol and cyclopropylazole derivatives with three stereogenic carbons in the small cycle are obtained via a highly diastereoselective formal nucleophilic substitution of bromocyclopropanes. The chiral center at C-2 in bromocyclopropane dictates the configuration of the other two stereocenters that are successively installed via a(More)
An efficient [4+4] cyclodimerization of cyclopropenemethanols operating via a two-fold strain release-driven addition of alkoxides across the double bond of cyclopropenes was investigated. This chemo- and diastereoselective transformation provided previously unknown 2,7-dioxatricyclo[7.1.0.0(4,6)]decane scaffolds.
The synthesis of a functionalized spiropiperidine via a tandem ring closing metathesis strategy is described, furthermore, the regio- and stereoselective functionalization of this compound has been achieved through a novel nitrogen-directed epoxidation reaction.
