Bioinspired palladium(II)-catalyzed intramolecular cyclization of aminoacidderivatives containing a vinyl iodide moiety by C−H activation enabled rapid access to a wide range of functionalized proline derivatives with an exocyclic double bond. Such functionalized prolines were used as intermediates for the total synthesis of several natural products: lucentamycin A, barmumycin, oxotomaymycin, and
仿生钯 (II) 催化的通过 C-H 活化对含有碘乙烯部分的氨基酸衍生物进行分子内环化,可以快速获得具有环外双键的各种功能化脯氨酸衍生物。这种功能化的脯氨酸被用作几种天然产物全合成的中间体:光亮霉素 A、巴木霉素、氧代梅霉素和氧代原霉素。

The present invention provides a tomaymycin biosynthetic gene cluster of
Streptomyces
species FH6421, and its use for producing 11-de-O-methyltomaymycin.
the pyrrolo-1,4-benzodiazepine family, was synthesized using a short and efficient route. The key construction of the seven-memberedring by amide bond formation was realized via a chemoselective Ar-NO2 reduction using TiCl3 under acidic conditions, followed by a spontaneous cyclization. This synthesis was easily scaled up to 80 g, and it should be amenable to the production of larger quantities.
