Thiol groups can be reductively eliminated at room temperature by a photochemical method which makes use of triethylboron, triethylphosphite and visible light. Thus, after treating l-Cys 1a, d-Pen 1b, l-Cys-OMe 1c and glutathione (γ-l-Glu-l-Cys-Gly) 3, the corresponding desulfurized compounds l-Ala 2a, d-Val 2b, l-Ala-OMe 2c and γ-l-Glu-l-Ala-Gly 4, respectively, are prepared in high yields and with
硫醇基团可以在室温下通过光化学方法被还原消除,该光化学方法利用三乙基硼,亚磷酸三乙酯和可见光。因此,在处理l-Cys 1a,d-Pen 1b,l-Cys-OMe 1c和谷胱甘肽(γ-1-Glu-1-Cys-Gly)3之后,相应的脱硫化合物l-Ala 2a,d-Val 2b,1-丙氨酸- OME 2C和γ-1-谷氨酸-1-丙氨酸-甘氨酸4,分别以高收率和配置的保留制备。
