identified as zealactone 1a/b and zeapyranolactone. We recently disclosed the first total synthesis of zealactone 1a/b together with its biological activity in corn. Herein, we describe the design and synthesis of simplified analogues of both corn-derived strigolactones with their bioavailability in soil and their biological activities. These compounds would be potential leads for the development of synthetic
独脚金内酯是植物激素之一,对植物生长发育具有多种活性。由于这些独脚金内酯活性与作物产量高度相关,因此独脚金内酯的使用可能是现代可持续农业中一项有前途的技术。玉米根分泌物中的主要独脚金内酯已被鉴定为玉米内酯 1a/b 和玉米吡喃内酯。我们最近首次公开了玉米内酯 1a/b 的全合成及其在玉米中的生物活性。在此,我们描述了两种玉米衍生的独脚金内酯的简化类似物的设计和合成及其在土壤中的生物利用度及其生物活性。这些化合物将成为开发合成独脚金内酯的潜在线索,用于更可持续的作物生产的农艺用途。
