A new one-pot tandem aldol process is described in which a secondary epoxy silyl ether is converted into the 1,5-bis-silyloxy-3-alkanone in good yield. Thus, treatment of the epoxy silyl ether8with TBSOTf and base affords the silyl enol ether9via non-aldol aldol rearrangement and addition of benzaldehyde and TBSOTf gives the ketone10with 4:1 syn selectivity. The diastereoselectivity changes to an anti preference for most aldehydes. This anti selectivity overwhelms the normal Felkin−Ahn preference; namely, the 1,5-anti isomer predominates even when it is anti-Felkin−Ahn.
