The first Pd-catalyzed alkylation of (iso)quinolines and arenes is reported. The readily available and bench-stable 2-acylpyridine compounds were used as an alkylation reagent to form the structurally versatile alkylated (iso)quinolines and arenes. The method affords a convenient pathway for the introduction of alkyl groups into organic molecules.
A manganese-catalyzed cross-coupling reaction of heterocyclic chlorides with aryl- as well as alkylmagnesium halides has been developed. The reaction provides a variety of heterocyclic compounds under mild and practical reaction conditions using low amounts of manganese chloride as catalyst.

discovery programmes and natural product synthesis. Herein, we report the photocatalytic construction of 2,7-diazabicyclo[3.2.1]octanes (bridged 1,3-diazepanes) via a reductive diversion of the Minisci reaction. The fused tricyclic product is proposed to form via radical addition to the C4 position of 4-substituted quinoline substrates, with subsequent Hantzsch ester-promoted reduction to a dihydropyridine

This disclosure relates to novel compounds comprising a zwitterionic trifluoroborate prosthetic group which target prostate-specific membrane antigen (PSMA), e.g. in prostate cancer. The compounds have Formula I, wherein each Rl is an anionic group, L is a linker and R2BF3 is - N(R3)2CH2BF3, a pyridinium group substituted with BF3 or methyl BF3, or an azole group substituted with methyl BF3. Methods and uses of imaging and treating PSMA-expressing cancers are also disclosed.
