Indium-mediated reaction of 1,3-dichloro- and 1,3-dibromopropenes with carbonyl compounds. Generation of novel 3,3-diindiopropene

Indium-mediated reaction of 1,3-dichloropropene with aldehyde gave syn-chlorohydrin predominantly. A similar reaction of 1,3-dibromopropene gave vinyloxirane and homoallyl alcohol; the former is formed from γ-bromoallylindium via the corresponding bromohydrin, and the latter is considered to be derived from a unique allylic diindium reagent, 3,3-diindiopropene.

Direct synthesis of Z-alkenyl halides through catalytic cross-metathesis

Olefin metathesis has had a large impact on modern organic chemistry, but important shortcomings remain: for example, the lack of efficient processes that can be used to generate acyclic alkenyl halides. Halo-substituted ruthenium carbene complexes decompose rapidly or deliver low activity and/or minimal stereoselectivity, and our understanding of the corresponding high-oxidation-state systems is limited. Here we show that previously unknown halo-substituted molybdenum alkylidene species are exceptionally reactive and are able to participate in high-yielding olefin metathesis reactions that afford acyclic 1,2-disubstituted Z-alkenyl halides. Transformations are promoted by small amounts of a catalyst that is generated in situ and used with unpurified, commercially available and easy-to-handle liquid 1,2-dihaloethene reagents, and proceed to high conversion at ambient temperature within four hours. We obtain many alkenyl chlorides, bromides and fluorides in up to 91 per cent yield and complete Z selectivity. This method can be used to synthesize biologically active compounds readily and to perform site- and stereoselective fluorination of complex organic molecules.

Synthesis of γ-functionalized allyltrichlorosilanes and their application in the asymmetric allylation of aldehydes

Isomerically pure trans-and cis-γ-bromoallyltrichlorosilanes 4 and 5 have been synthesized and shown to react with aromatic aldehydes 1 in the presence of Lewis-basic catalysts (e.g., DMF) to produce the corresponding anti-and syn-allylbromohydrins 8 and 9, respectively, as single diastereoisomers. With BINAPO 25 as a chiral catalyst, promising enantioselectivity (≤50% ee) has been attained.

Cr(Salen)-catalyzed addition of 1,3-dichloropropene to aromatic aldehydes. A simple access to optically active vinyl epoxides.

[reaction: see text]. Chiral Cr(Salen) complex (1) prepared in situ from CrCl3 promotes the enantioselective addition of 1,3-dichloropropene to aromatic aldehydes in the presence of Mn as the stoichiometric reductant and Me3SiCl as a scavenger. The result

Either γ-syn- Or γ-anti-selective palladium-catalysed carbonyl allylation by mixed (E)- and (Z)-l,3-dichloropropene with tin(II) halides

Palladium-catalysed carbonyl allylations by mixed (E)- and (Z)-1,3-dichloropropene with SnI2-Bu4NI and SnCl2 diastereoselectively produce syn and anti 1-substituted 2-chlorobut-3-en-1-ols, respectively. These are transform
