Abstract: | An efficient and simple method using alkaline ferricyanide for converting the NCH2CH2OH group-containing alkaloid derivatives into their “normal”- and “iso-type”-oxazolidine ring-containing alkaloids has been developed. This is the first one-step oxidation method which affords both types of oxazolidine rings simultaneously. |
