在本文所述的 SAR 研究中,分析、探索和优化通过与 RCAR/(PYR/PYL) 受体蛋白(植物激素脱落酸的关键生化靶标)相互作用而显示出良好的初始体外活性的先导结构。在深入的 SAR 研究过程中,确定了几种新的强效磺酰胺先导结构,与最初的先导结构相比,它们具有更高的靶点亲和力,更重要的是,在大面积作物油菜和小麦中,它们在体内对抗干旱胁迫的功效有所提高。

The reaction of N-methylspiro[anthracene-oxazolidine] with spiro[cyclopropane-3,3′-indolin]-2-ones in the presence of MgI2 formed the corresponding spiro[pyrrolidine-3,3′-indolin]-2-ones in 42–65% yields. The use of N-benzylspiro[anthracene-oxazolidine] in this reaction led to the formation of a mixture of the corresponding N-methyl- and N-benzylpyrrolidines.
