Synthesis of 6,7-dehydroartemisinic acid

Sy, Lai-King, Brown, Geoffrey D.·2001·Journal of the Chemical Society, Perkin Transactions 1

Abstract

The natural product 6,7-dehydroartemisinic acid from Artemisia annua has been synthesized in four steps from artemisitene, which was in turn prepared in four steps from commercially available artemisinin. The forward synthesis involves the acid degradation of artemisitene and some comparisons are made between the products from this reaction and the more extensively studied acid degradation reaction of its 11,13-dihydro analogue, artemisinin.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Artemisitene can be obtained readily by chemical transformations of artemisinin, and a partial synthesis of artemisitene from artemisinic acid (473) has been reported.

    “although artemisitene can be obtained readily by chemical transformations of artemisinin [165,213,241,242]; and a partial synthesis of artemisitene from artemisinic acid (473) has also been reported [243].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
