摘要
The hydroxy ketone natural product kurasoin B is synthesized using a phase-transfer-catalyzed alkylation reaction with benzyloxyacetyl imidazole. A biscinchonidinium dimethylnaphthalene catalyst allowed for high yield and near complete selectivity (99% ee) for the S-product using 3-methylbromoindole as the electrophile.
