实验步骤: A solution of (1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalene-4-carboxylic acid (111 mg, 0.50 mmol), TBTU (177 mg, 0.55 mmol) and ethyl-diisopropylamine (282 μL, 1.65 mmol) in DMF (15 mL) is allowed to stand at rt for 20 min. A solution of 4-aminomethyl-phenol hydrochloride (88 mg, 0.55 mmol) and ethyl-diisopropylamine (94 μL, 0.55 mmol) in DMF (1.5 mL) is added and the mixture is allowed to stand at rt for 3 h. After the addition of formic acid (0.2 mL), the mixture is separated by HPLC to afford (1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalene-4-carboxylic acid 4-hydroxy-benzylamide (45 mg) as a colourless oil. LC-MS: tR=0.96 min, [M+1]+=328.17. to stand at rt for 3 h the mixture is separated by HPLC
