The C(1) to N(14) segment of the potent thrombin inhibitor cyclotheonamide A was prepared from L-arginine, L-proline, and L-asparagine. The arginine backbone was extended via a cyanohydrin, and the usual diaminopropanoic acid residue was obtained from hypervalent iodine oxidation of the asparagine side chain.
由L-精氨酸,L-脯氨酸和L-天冬酰胺制备强效凝血酶抑制剂环硫酰胺A的C(1)至N(14)片段。精氨酸主链通过氰醇延伸,并且通常的二氨基丙酸残基是从天冬酰胺侧链的高价碘氧化获得的。
