The synthesis of both enantiomers of the trans-3-acylamino-4-hydroxymethyl-2-oxo-1-sulfoazetidines 3a, b and 4a, b is described. The enantiomers of 4-hydroxymethyl-2-azetidinone, 7a and 7b, were chosen as starting materials, and the latter was synthesized from L-malic acid. For sulfonation at the N-1 position, the new amidine-N-sulfonic acid 6 was prepared and used. The preparation and antibacterial properties of the 4-acetoxymethyl derivatives 22a, b and 23a, b are described.
本文介绍了反式-3-乙酰氨基-4-羟甲基-2-氧代-1-磺酸基氮杂环丁烷 3a, b 和 4a, b 的两种对映体的合成。4- 羟甲基-2-氮杂环丁酮的对映体 7a 和 7b 被选作起始原料,后者由 L-苹果酸合成。为了在 N-1 位进行磺化,制备并使用了新的脒-N-磺酸 6。文中介绍了 4-乙酰氧甲基衍生物 22a, b 和 23a, b 的制备和抗菌特性。
