recently identified, potent germination stimulant 3-methyl-2H-furo[2,3-c]pyran-2-one and analogous compounds, using carbohydrate substrates, is described. D-Xylose and D-glucuronic acid γ-lactone were used in the preparation of the parent heterocycle and its 5-methoxycarbonyl analogue, respectively. These compounds were elaborated using various methods to furnish the natural product and a suite of its
描述了使用碳水化合物底物合成最近发现的有效发芽刺激剂 3-methyl-2H-furo[2,3-c]pyran-2-one 和类似化合物的有效合成途径。D-木糖和D-葡萄糖醛酸γ-内酯分别用于制备母体杂环及其5-甲氧基羰基类似物。这些化合物是使用各种方法精心制作的,以提供天然产物及其一系列类似物。因此,萌发刺激剂是从廉价的、可商购的 1,2-O-异亚丙基-D-呋喃木糖以 30% 的总收率分九步以多克规模制备的,大大改进了迄今为止公布的唯一方法。 © Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
