Adian-5-ene ozonide

Several stable triterpenoid natural products containing 1,2,4-trioxolanes have been characterized, for example adian-5-ene ozonide (175) isolated from the fern Adiantum monochlamys <90CPB79,... [Pg.618]

Two naturally occurring ozonides, gilvanol (213) from Quercus gilva and adian-5-ene ozonide (214) from the leaves of Adiantum monochlamys, °° have been isolated. Their structures were readily confirmed by the action of ozone on hop-17(2l)-en-3jS-ol and adian-5-ene respectively. Amphistictinic acid (215), from the lichen Pseudocyphellaria amphisticta, is 15a-acetoxy-22-hydroxy-hopan-24-oic acid. The structure of the 6a,7a,22-trior previously reported from the lichen P. mougeotiana has been revised to 6a,7/3,22-tri-hydroxyhopane (216). The Tlj8,22-dior isolated from the same source has been shown to be a mixture of 7/8,22- (217) and 15a,22-dihydroxyhopane (218). [Pg.215]
