STRUCTURE AND SYNTHESIS OF MURRAPANINE, A NOVEL SKELETAL INDOLE-NAPHTHOQUINONE ALKALOID AND CYTOTOXIC PRINCIPAL FROM MURRAYA PANICULATA VAR. OMPHALOCARPA

A novel skeletal cytotoxic indole-naphthoquinone alkaloid, murrapanine, has been isolated from the root bark of Murraya paniculata var. omphalocarpa and its structure has been established from spectral data and single-crystal X-ray analysis; the synthesis of murrapanine from indole-3-aldehyde is also described.

Antifertility Agents: A Synthetic Entry to Yuehchukene Analogues; Stereoselective Synthesis of 7,7-Bis-nor-yuehchukene via 9-Methyl-6-oxo-6aβ-7,8,10aβ-tetrahydroindenoindole

Intermolecular Diels-Alder reaction and polyphosphate ester-catalysed intramolecular acylation are used in a synthetic approach to 9-methyl-6-oxo-6aβ-7,8,10aβ-tetrahydroindenolindole (15),the basic structure of the antifertility agent yuehchukene (

Biomimetic Synthesis of Yeuhchukene

The title compound (1), a potential antifertility agent, can be synthesised by Diels-Alder cyclization of 3-isoprenylindole (2).
