1,4-Functionalisatio of cycloocta-1,3-diene using a nitroso-cycloaddition strategy is followed by intramolecular cyclisation to yield 9-azabicyclo[4.2.1]nonanes (homotropanes) and -non-7-enes (homotrop-7-enes); the approach can be adapted to allow ac

1,4-Functionalisation of cycloocta-1,3-diene using a nitroso-cycloaddition strategy is followed by intramolecular displacement by nitrogen to yield the 9-methyl-9-azabicyclo[4.2.1]nonane (homotropane) and -non-7-ene (homotrop-7-ene) systems and N-ben

Trop-6-ene (8-methyl-8-azabicyclo[3.2.1]oct-6-ene) and substituted N-benzylnortrop-6-enes are synthesised. N-Debenzylation of tropanes fails using a wide variety of non-hydrogenolytic conditions despite effective application in model piperidine deriv

Aryl bromides and iodides in the presence of catalytic amounts of a palladacycle derived from acetophenone oxime and 2 equiv of potassium acetate react with ethylene under ambient pressure (15–30 psi) to give the corresponding vinylarenes. The reac

Mono- and 2,2'-disubstituted terminal alkenes can be isomerized into the more stable internal (Z)- and (E)-alkenes by treating them with catalytic amounts of [(allyl)PdCl](2) or [(allyl)NiBr](2), a triarylphosphine, and silver triflate at room temper

α-Alkylstyrenes undergo efficient hydrovinylation (addition of ethene) in the presence of a nickel catalyst prepared from [(ally])NiBr] 2 , Na + [BAr 4 ] ― [Ar = 3,5-bis(trifluoromethyl)phenyl], and a phosphoramidite ligand giving products in exce

A three-step procedure for the synthesis of 2-arylpropionic acids (profens) from vinyl arenes in nearly enantiomerically pure form has been developed. Excellent yields (>97%), regioselectivities (>99%), and enantioselectivities (>97% ee) for the desi
