?-Siloxy-?-haloketones through highly diastereoselective single and double mukaiyama aldol reactions.

ABSTRACT: Double-action haloketones: A super silyl group enabled the first highly diastereoselective Mukaiyama aldol reactions of ?-chloro- and ?-fluoroketones with a wide range of aldehydes, providing anti-?-siloxy-?-haloketones. This process is compatible with one-pot double-aldol methodology and allows for rapid access to new halogen-modified polyketide fragments bearing up to four contiguous stereocenters.
