A new type of terpenoid cyclization directed by a β-keto ester moiety has been developed, which proceeded by manganese(III)-initiated oxidation of the β-keto ester, followed by an intramolecular hetero Diels-Alder reaction with the terpenoid chain. This reaction produces polycyclic dihydropyrans in high yields and stereoselectivities under mild conditions. Copyright
Selective C - S bond formation via Fe-catalyzed allylic substitution

In contrast to the formation of C - O and C - N bonds it was only recently that the selective C - S bond formation by means of transition metal complexes moved more into the center of research. This is somewhat surprising given the fact that the sulfur at
