“…7 To establish more complex reaction sequences including CC coupling steps, polymer‐supported carbanion equivalents would be an ideal addition to the synthetic repertoire in polymer‐assisted synthesis. Lithiated dithioacetals8–10 have been described as polymer‐supported carbanion equivalents, however, these reagents are strongly basic and are thus of no use for the efficient parallel synthesis of sensitive products. Ideally, the successful method should allow reactions with easily available building blocks, under smooth, neutral conditions, and further derivatization after the CC coupling step.…”
