title: Designer discodermolide segments via ozonolysis of vinyl phosphonates.
abstract: To apply our collection of enantiopure 7-ring vinyl sulfones to probe the anticancer SAR of a series of computer-designed (+)-discodermolide analogs, the ozonolytic reactivity of transposed cyclic vinyl phosphonates was explored. Successful preparation of the desired aldehyde-esters and lactones from vinyl phosphonates via an oxidative cleavage-phosphite/methanol exchange sequence is described.
