cyclo-(L-2-Aminobutanoyl-L-phenylalanyl)(1; R = Et), an unnatural analogue of the gliotoxin (2; R = CH2OH) precursor, cyclo-(L-Phe-L-Ser)(1; R = CH2OH), is transformed in Gliocladium deliquescens into the titled compound (4; R = Et) showing that biosynthetic introduction of sulphur may proceed without prior N-methylation or oxidative cyclisation of the phenyl group.
环-(L -2-氨基丁酰基-L-苯丙氨酰基)(1 ; R = Et),胶体毒素(2 ; R = CH 2 OH)前体的非天然类似物,环-(L -Phe- L -Ser)(1; R = CH 2 OH)在水溶胶草中转化为标题化合物(4; R = Et),表明硫的生物合成引入可以在没有预先的N-甲基化或苯基的氧化环化的情况下进行。
