## Abstract Carbon‐13 spectra of a series of 26 unsaturated ketones (__ortho__‐ and __para__‐cyclo‐hexadienones and corresponding open‐chain analogues) have been measured by __Fourier__‐transform. Pulse spectroscopy. A complete analysis has been achieved by means of double resonance experiments usi

An enantioselective synthesis of a,b-unsaturated gand d-lactams was proposed based on a simple strategy using the initial preparation of cis vinylogous aminoesters by the Horner reaction followed by a mild intramolecular cyclisation.
The Rh-DuPHOS and Rh-BPE catalyzed hydrogenation of IS-substituted ¢x,[~,y,8-unsaturated amino acids establishes two contiguous stereogenic centers simultaneously. Both high regioselectivity and good to excellent enantioselectivity have been demonstrated in this process leading to I~-branched allyl
