2-disulfides, using chemical and enzymatic (peroxidase, monooxygenase, dioxygenase) oxidation methods and chiral stationary phase HPLC resolution of racemic thiosulfinates. Enantiomeric excess values, absolute configurations and configurational stabilities of chiral thiosulfinates were determined. Methyl phenyl sulfoxide, benzo[c]thiophene cis-4,5-dihydrodiol and 1,3-dihydrobenzo[c]thiophene derivatives were
通过化学和酶促(过氧化物酶,单加氧酶,双加氧酶)氧化方法和手性固定相HPLC拆分外消旋的硫代亚磺酸盐,通过环状1,2-二硫化物的不对称硫氧化获得对映体富集和对映体纯的硫代亚磺酸盐。测定了手性硫代亚磺酸盐的对映体过量值,绝对构型和构型稳定性。当非环状和环状1,2-二硫化物用作假单胞菌的底物时,甲基苯基亚砜,苯并[ c ]噻吩顺式-4,5-二氢二醇和1,3-二氢苯并[ c ]噻吩衍生物是分离出的未预期类型的代谢物。恶臭株。提出了可能的生物合成途径,用于由1,4-二氢苯并-2,3-二噻吩生产代谢物,包括新型的顺式-二氢二醇代谢物,该代谢物也衍生自苯并[ c ]噻吩和1,3-二氢苯并[ c ]噻吩。
