Asymmetric total synthesis of S-(+)-argentilactone (2) was accomplished, us
ing methyl-alpha -D-glucopyranoside (3) as carbohydrate template. Benzylide
ne acetal 5 was hydrolysed with (BuOOH)-Bu-1/AlCl3 and further manipulated
to produce the aldehyde 10. A Wittig reaction and subsequent oxidation of t
he anomeric position yielded the target argentilactone.
