The synthesis of the abeo-abietane-type diterpenoids, i.e., (-)-dichroanal B, (-)-dichroanone, and taiwaniaquinone H, was achieved by using the intramolecular asymmetric Heck reaction. Our synthetic routes required fewer steps and gave a much higher

International audience; Asymmetric spiro cyclization of a pyrrolidine derivative was used as a key step for constructing novel rigid diamines. Aselected example has proved its utility as a chiral nonmetallic catalyst in a Michael reaction.

A study of the anodic oxidation of indolic compounds in the tetrahydro-β-carboline series is described. Methoxylation at the a position of the C-3 indole ring was observed furnishing a convenient access to variously substituted products at that posi
