Me 4-(1-methylpyrrolidin-2-yl)-3-oxobutanoate and hygrine are important biosynthetic intermediates for tropane alkaloids. A concise method to synthesize these two compounds from the key intermediate N-methylpyrrolinium cation has been developed. Me 4-(1-methylpyrrolidin-2-yl)-3-oxobutanoate and hygrine were obtained in four and six steps from com. available 4,4-diethoxybutylamine with overall yields of 42% and 25%, resp.
