Application
Electrophile employed in a new synthetic approach to polyketide structural units.
General description
Iodine monobromide is an interhalogen compound used as an electrophile in the synthesis of polyketide structural units.
Iodine monobromide (IBr) is a powerful iodinating agent employed in organic synthesis. IBr is commonly used in cleavage of carbon–metal bonds, electrophilic addition to alkenes, α-bromination of steroidal ketones and aldehydes, and in diastereoselective cyclizations of homoallylic carbonates.

[Structure: see text] A strategically novel approach to the formation of syn-1,3-diol mono- and diethers through electrophilic activation of homoallylic alkoxymethyl ethers has been developed. The resulting polyketide-like synthetic fragments are generated in good yield and with excellent stereocontrol. A
