Autor: Tharun K. Kotammagari, Sweta Misra, Sayantan Paul, Sunita Kunte, Rajesh G. Gonnade, Manas K. Santra, Asish K. Bhattacharya

Publikováno v: Beilstein Journal of Organic Chemistry, Vol 19, Iss 1, Pp 204-211 (2023)

The total synthesis of racemic incarvilleatone has been achieved by utilizing unexplored accelerated Rauhut–Currier (RC) dimerization. The other key steps of the synthesis are oxa-Michael and aldol reactions in a tandem sequence. Racemic incarville

Dimerization Strategies for the Synthesis of High-Order Securinega Alkaloids

Autor: Joonoh Park, Seongmin Jeon, Jongsun Lee, Sunkyu Han, Gyumin Kang, Mu-Hyun Baik

Publikováno v: The Journal of Organic Chemistry. 84:1398-1406

We describe different modes of dimerization of various α',γ-dioxyenone derivatives with potential applications to the synthesis of high-order securinega alkaloids. We learned that the relative stereochemical relationship between α'- and γ-hydroxy

Serendipitous Discovery of a Cascade Approach to Perhydrodibenzofuranones Related to the Natural Product Incarviditone

Autor: Stephania Christou, Alyn C. Edwards, Ian J. Stratford, Robin G. Pritchard, Roger C. Whitehead, Peter Quayle

Publikováno v: Synlett. 25:1263-1266

The unexpected discovery of an eliminative deprotection and cyclodimerization cascade reaction sequence led to the preparation of a series of perhydrodibenzofuranones that bear a structural resemblance to the natural product incarviditone. One of the

Publikováno v: Angewandte Chemie International Edition. 52:5314-5318

Chiral cis-hydrobenzofurans represent a uniquemotif existing in numerous natural products, for instance, isoambrox, haterumaimide I, rosenonolactone, incarviditone, and millingtonine A (Scheme 1a). Owing to their diverse biological activities, a grea

Incarviditone: A Novel Cytotoxic Benzofuranone Dimer fromIncarvillea delavayiBureau et Franchet

Autor: Yong-Qing Su, Yun-Heng Shen, Lingyi Kong, Yu-Qi Chen, Wei-Dong Zhang

Publikováno v: Chemistry & Biodiversity. 6:779-783

A novel benzofuranone dimer, named incarviditone (1), along with known rengyolone (2), was isolated from Incarvillea delavayi Bureau et Franchet. The structure of the new compound was elucidated on the basis of spectroscopic methods, especially 2D-NM
