The chiral sulphoxide 1 was synthesized from 10-mercaptoisoborneol via diastereoselective oxidation. The dienophile 1 reacted with cyclopentadiene in the presence of a Lewis acid to give the adducts 7 and 8 with high diastereoselectivity (∼100%). D

Treatment of Sendai virus with p-azidophenyl-6-chloro-6-deoxy-beta-D-glucopyranoside (APG) caused chemical modification of the viral envelope under UV irradiation, which did not affect the hemagglutinin activity of the virus but inhibited the hemolyt
