  The marine alkaloids (−)‐lepadins A–C and (+)‐lepadin D, belonging to two diastereoisomeric series, were synthesized from an (R)‐phenylglycinol‐derived tricyclic lactam via a common cis‐decahydroquinoline intermediate. Crucial aspects of the synthesis are the stereochemical control in the assembly of the cis‐decahydroquinoline platform, in the introduction of the C2 methyl and C3 hydroxy substituents

  reactions of sulfenyl chloride derivatives of rhodium and ruthenium acetylacetonates as well as of chromium(III) and cobalt(III) β-diketonates (with β-phenyl groups) have been studied. The studied complexes can participate in the substitution and addition reactions. As compared with the previously studied sulfenyl chlorides of acetylacetonate complexes, many side processes occur in the case of β-phenyl chelates;
