Total synthesis of milbemycin E: Resolution of the C(1)-C(10) fragment and final assembly

The racemic hydroxycyclohexanone (±)-7, prepared by the Robinson addition of the keto ester 5 to 3-methylbut-3-enone 6, has been reduced stereoselectively to give the racemic cyclohexanediol (±)-8. This has been resolved by fractional crystallisation of t

A Total Synthesis of Milbemycin E

Milbemycin E (1) and 3,4-dihydromilbemycin E (34) have been synthesized, the C(1)-C(10) fragment being prepared using a stereoselective Robinson annelation.
