Stereocontrolled syntheses of two potent antiviral agents, beta-L-FD4C and beta-L-FddC, were accomplished both in 10-step sequences, with an overall yield of 27% and 25%, respectively. It is worthwhile to mention that the introduction of a phenylseleno moiety to the C-2 alpha position of the lactone 4 can now be performed in a stereocontrolled fashion, providing the key intermediate 5 alpha in 75% yield.
