Ring-opening metathesis phase-trafficking (ROMpt) synthesis: multistep synthesis on soluble ROM supports.
The use of ring-opening metathesis (ROM) oligomers as soluble supports for a multistep reaction sequence is described. A Mitsunobu reaction followed by an in situ ROMP-mediated phase-trafficking purification is utilized to generate soluble ROM oligomers that are isolated via precipitation with methanol. Once formed, the ROM oligomers serve as soluble supports for further solution-phase reactions, including a ring-closing metathesis. After each step, the support-bound products are isolated by precipitation with a suitable solvent. [reaction--see text]
