with all types of substitution patterns. In general, the vicinal difluoride products are produced with high diastereoselectivities. The observed sense of stereoinduction implicates anchimericassistance pathways in reactions of alkenes bearing neighboring Lewis basic functionality.

The present invention relates to novel dopamine D2 receptor ligands. The invention further relates to functionally-biased dopamine D2 receptor ligands and the use of these compounds for treating or preventing central nervous system and systemic disorders associated with dysregulation of dopaminergic activity. The present invention relates to novel compounds that modulate dopamine D2 receptors. In particular, compounds of the present invention show functional selectivity at the dopamine D2 receptors and exhibit selectivity downstream of the D2 receptors, on the 0- arrestin pathway and/or on the cAMP pathway.

for the isomerization of acyclic allylic alcohols into β-functionalized ketones via 1,3-alkyl transposition. This reaction proceeds via light-driven proton-coupled electron transfer (PCET) activation of the O−H bond in the allylic alcohol substrate, followed by C−C β-scission of the resulting alkoxy radical. The transient alkyl radical and enone acceptor generated in the scission event subsequently

exo-isomers of N-Boc-protected spiro[2′,2′-difluorocyclopropane-3′,2′-tropanes] were synthesized in 62–83% yield via absolutely diastereoselective cycloaddition of CF2, generated in situ from Me3SiCF3/NaI in refluxing THF, to double bonds of 3-alkylidenetropanes. Standard removal of Boc protecting groups afforded corresponding exo-spiro[2′,2′-difluorocyclopropane-3′,2′-tropane] hydrochlorides in 82–94%
