The visible-light-driven preparation of (hetero)aryl stannanes was carried out under both photocatalyst- and metal-free conditions via irradiation of arylazo sulfones in the presence of hexaalkyldistannanes. The reaction shows a high efficiency and a wide substrates scope. The resulting crude organotin derivatives can be directly employed in a Stille protocol.

Sandmeyer-type stannylation: Stille coupling is one of the most powerful coupling reactions for C-C bond formation, whereas there are only limited methods to access aryl stannane compounds. A mild stannylation process based on a Sandmeyer-type transformation using aromatic amines as the starting materials is described. DCE: 1,2-dichloroethane. Copyright

F-18 and H-2 dual-labeled altanserin (3, [18F]d-ALT), a novel PET tracer for 5-HT(2A) receptors with metabolically resistant properties, was synthesized by [18F]fluoride displacement of the corresponding deuterated nitro precursor in 32% yield (EOB) in 108 min with radiochemical purity 95% and specific activity > 1000 mCi/μmol (EOS). The key intermediate ethyl N-(2-chloroethyl-2,2-d2)carbamate (7) was obtained by LiAID4 reduction of a glycine ester (93%), chlorination and carbamoylation (79%). 4-(4-Nitrobenzoyl)piperidine (13) was synthesized (60%) by improving the published coupling reaction of p-nitrophenyltrimethylstannane (10), obtained from p-iodonitrobenzene and (CH3)6Sn2 (94%), with 1-benzoylisonipecotic acid chloride (11) followed by acid hydrolysis. 13 was alkylated with 7 (82%), hydrolyzed and condensed with methyl o-isothiocyanatobenzoyate to provide with the precursor deuteronitroaltanserin (4, 75%).
