The present invention relates to methods for forming dicarba bridges in organic compounds. This involves the use of a pair of complementary metathesisable groups on the organic compound, and subjecting the compound to cross-metathesis under microwave radiation conditions. In an alternative, the compounds contain a turn-inducing group between the pair of cross-metathesisable groups to facilitate the cross-metathesis.
An optically active octahydroindole, the core unit of aeruginosins (Choi) was synthesized. The Diels–Alder reaction of Danishefsky's diene with methyl (Z)-2-acetamido-2,4-pentadienoates provided the adducts regioselectively in good yield. The adducts were converted to the l-Choi precursor by asymmetric hydrogenation, followed by acid cyclization.

described. A sequence of ruthenium-catalyzedcrossmetathesis and rhodium-catalyzed hydrogenation of nonproteinaceous allylglycine derivatives has been developed to achieve high-yielding and unambiguous formation of diaminosuberic acid derivatives. Allylglycine derivatives readily undergo ruthenium-catalyzedmetathesis and hydrogenation to yield diaminosuberic acid derivatives in near quantitative yield
