A bisvinylogous Mukaiyama aldol reaction using oxazaborolidinones as a source of chirality was developed. This methodology allows the fast assembly of conjugated dienols by expanding the vinylogy principle by two additional carbons, and can be conducted using a readily available Lewis acid at reasonable reaction times. A broad range of aromatic and aliphatic aldehydes can be used providing access to complex building blocks for polyketide synthesis.
