Rhodium-catalyzed intermolecular chelation controlled alkene and alkyne hydroacylation: synthetic scope of beta-S-substituted aldehyde substrates.
The use of beta-S-substituted aldehydes in rhodium-catalyzed intermolecular hydroacylation reactions is reported. Aldehydes substituted with either sulfide or thioacetal groups undergo efficientExpand

Catalytic enantioselective desymmetrisation as a tool for the synthesis of hodgkinsine and hodgkinsine B.
Two palladium-catalysed amination protocols are deployed in the desymmetrisation of the complex dimeric alkaloid meso-chimonanthine. The power of these transformations is showcased in an efficientExpand

Rhodium-catalyzed reductive aldol reactions using aldehydes as the stoichiometric reductants.
Chelated acyl rhodium hydrides, generated from the addition of [Rh(dppe)]ClO4 to beta-sulfide-substituted aldehydes, can function as the stoichiometric reductants in reductive aldol processes.Expand

Scalar coupling between the 15N centres in methylated 1,8-diaminonaphthalenes and 1,6-diazacyclodecane: to what extent is 2HJNN a reliable indicator of N-N distance?
The scalar couplings between hydrogen bonded nitrogen centres ((2H)J(NN)) in the free-base and protonated forms of the complete series of [(15)N(2)]-N-methylated 1,8-diamino naphthalenes in [D(7)]DMFExpand
