containing six contiguous stereogeniccentres) in which the (Z)-enol isobutyrate units remained intact were obtained. After suitable protection, these were converted into their corresponding lithium (Z)-enolates, which could react with isopropylidene D-glyceraldehyde [(+)-9] to give aldol products that were reduced to various stereodecads (polyketides with ten contiguous stereogeniccentres). The disclosed chemistry
