The tandem cyclohydrocarbonylative/CO insertion of alpha-imino alkynes employs CO, H2, and catalytic quantities of zwitterionic rhodium complex (eta6-C6H5 BPh3)-Rh+(1,5-COD) and triphenyl phosphite affording aldehyde substituted pyrrolinones in 67-82% yields. This unique transformation is readily applied to imino alkynes containing alkyl, alkoxyl, vinyl, and aryl substituents. The ability to prepare highly functionalized pyrrolinones makes this an attractive route to these important and versatile pharmaceuticals.

A series of donor-pi-acceptor systems incorporating a tetrathiafulvalene moiety as the donating unit have been designed and synthesized. The efficiency of the imine (-C=N-) bond as a conjugated pi-linker in promoting intramolecular charge transfer is demonstrated and supported by calculations at the B3LYP/6-31G(d,p) level of theory. This property has been explored in the case of pyridyl-substituted systems which exhibit in particular a high binding affinity and selectivity for Pb2+ (log K = 3.5 in CH 2Cl2/CH3CN), as shown by UV/Vis and 1H NMR titrations as well as by remarkable colorimetric and electrochemical signaling.

A Wittig reaction employing Li(CD3)2CP(C 6H5)3 was used to prepare d6- farnesol and d6-geranylgeraniol. Reductive amination of aniline-2,3,4,5,6-d5 was used to prepare the unnatural isoprenoid analogues d5-anilinogeraniol and d5-anilinofarnesol. All of these deuterated isoprenols were elaborated into their diphosphate and cysteine thioether derivatives suitable for use as stable-isotope labeled standards for quantitative mass spectrometric analysis. Deuterated isoprenols d6-farnesol, d6-geranylgeraniol, d5- anilinogeraniol, d5-anilinofarnesol and their corresponding diphosphates and cysteine thioethers were synthesized.
