This has led to modification of some previous assumptions about the biodegradative route of botrydial. The [10-2H,15-2H]-botry-1(9)-4-diendiol (12) was transformed into dehydrobotrydienediol derivatives 13–15 but it was not incorporated into secobotryane skeleton (7). In addition, three new sesquiterpenoids have been isolated, which shed further light on the secondary metabolites of Botrytis cinerea

A newphytotoxin, botrydienal, and its two related metabolites, dehydrobotrydienal and deacetyldihydrobotrydial, were isolated from Botryotinia squamosa, and their structures were elucidated as 1, 2 and 3, respectively, on the basis of spectral analysis.

Eighteen compounds with a botryane skeleton have been obtained through chemical transformations of various toxins from the fungus Botrytis cinerea. During the course of these transformations, the C-10 carbon of the botryane skeleton was found to exhibit an interesting high regioselectivity to oxidizing and reducing agents. In addition, the cytotoxicity of 27 botryane derivatives was determined in vitro
