The syntheses of the marine sponge‐derived γ‐amino carboxylic acid dysibetaine CPa and five analogs in their racemic forms were successfully performed by taking advantage of an electron‐withdrawing N ‐(4‐nitrophenyl) group in the cyclopropanation reaction, the reductive ring opening of an imide, and the ethanolysis of an N ‐Boc‐protected imide.
