실험 절차

In a mixture of 3.5 ml of ethanol and 1.5 ml of water are dissolved 1.0 g of 4-(3-methylbutylidene)-1-cyclohexanone, 1.1 g of D-cysteine hydrochloride monohydrate and 0.52 g of sodium acetate. The resulting solution is stirred at ambient temperature for 2 hours. Water is added to the reaction mixture and the deposited crystal is collected by filtration. Thus, 0.81 g of (3S)-8-(3-methylbutylidene)-1-thia-4-azaspiro[4.5]decane-3-carboxylic acid is obtained as a colorless crystalline product.
