The known derivative of a-santonin (480) has been transformed into the three lactones (481)—(483) which, in turn, have been converted into arglanine (484), vulgarin (485), and C-4-epivulgarin (486) respectively. In a related study the ketone (487) has served as a synthetic precursor for douglanine (488) and ludovicins A (489) and B (490) (Scheme 62). ... [Pg.75]

Arborescin (586), a metabolite of Artemisia arborescens, has been synthesized (Scheme 59) from the eudesmanolide derivative (421) previously used in the synthesis of vulgarin " cf. p. 128). [Pg.150]

The cw-6j3-sesquiterpene lactones obtained by these methods have proved to be excellent substrates for synthetically useful biotransformations with different microorganisms. Incubation of compound 116, prepared from santonin (see Scheme 14), with Rhizopus nigricans (Scheme 16) cultures for 6 days yielded starting material 116 (48%), 4-e/>/-6)3-vulgarin (120) (8%), alcohol 131 (8%), and an 8j8-hydroxyl derivative 132 (11%) [25]. [Pg.74]

Full reports of the syntheses of frullanolide (558), " 3-oxodiplophyIlin (559), yomogin (560), dihydrocallitrisin (561), epialantolactone (562), epi-isoalantolactone (563), and atractylon (564) have been presented. Another synthesis of vulgarin (565) has been recorded. ... [Pg.75]
