(ELISA) to profile the interactions of nicotine haptens or hapten-protein conjugates with nicotine specific antibodies, both polyclonal and monoclonal. Another relies on computational modeling of the interactions between haptens and amino acid residues near the conjugation site of the carrierprotein to infer linker-carrier protein conjugation effect on antinicotine antibody response. Using these two in

Polyfunctionalized (E)-alk-1-enyl halides 3 were efficiently synthesized in high yields via a novel regio- and stereoselective X- (X = I or Br)-triggered ring-opening couplingreaction of cyclopropenes 1 with organic halides 2.

A stereospecificsynthesis and the gastric antisecretory and diarrheal activity of a 3E,5Z diene analogue of misoprostol are described. The key intermediate in the synthesis was an alpha chain truncated acetylene that was obtained by a cuprate/enolate capture procedure on the corresponding cyclopentenone. Palladium-catalyzed coupling of the acetylene with methyl 4-iodo-3(E)-butenoate provided the conjugated
γ-Phenylseleno α,β-unsaturated esters, prepared from α-phenylseleno aldehydes by Horner-Emmons reaction and treated with bromine or sulfuryl chloride, form adducts whose decomposition leads to α-halo β,γ-unsaturated esters in fair to good yields.

Depending upon the solvent and reaction conditions, reactions of the lithium dienolate 2 with 4-halocrotonate esters 3 gave largely the simple alkylation product 4, a mixture of diastereomeric cyclopropyl esters 5, or the halo 7-oxabicycloheptanones 6.
