Hydantocidin (12), a naturally occurring strong herbicide, was synthesized in 35.2% overall yield, with accompanying 5-epi-hydantocidin (12') in 9.6% overall yield via isothiocyanate (13) and spiro-hydantoin (10) from 2,3-O-isopropylidene-D-ribono-1,4-lactone (1). C-2-thioxo-hydantocidin (24) was also synthesized in 16.5% overall yield with accompanying 5-epi-C-2-thioxohydantocidin (24', 9.2% yield)
Hydantocidin(12)是一种天然存在的强力除草剂,通过异硫氰酸酯(13)和螺-乙内酰脲(10)的合成,以35.2%的总收率合成了伴有5-epi-hydantocidin(12')的总收率为9.6%。 3-O-异亚丙基-D-ribono-1,4-内酯(1)。还通过异硫氰酸酯(22)以16.5%的总收率合成了C-2-硫氧杂-羟基抗生物素蛋白(24),伴随着5-e-C-C-2-硫氧杂合羟基抗生物素蛋白(24',9.2%的产率)。
