(Reactions 1-4, 8 and 9). On the other hand, when no surfactant was added, the diastereoselectivity was high, but the reaction yield was extremely low (reaction 5). In addition, in systems using CTAB, a cationic surfactant, and Triton® X-100, a nonionic surfactant, high diastereoselectivity was obtained, but the reaction yield was low. (Reactions 6 and 7).
- SDS sodium benzenesulfonate having a long-chain alkyl group
