[reaction: see text] The first total synthesis of the C(3)-symmetric and biologically active natural product, (-)-xyloketal A, has been accomplished in one step from phloroglucinol (1,3,5-trihydroxybenzene) and (4R)-3-hydroxymethyl-2,4-dimethyl-4,5-dihydrofuran. This remarkably direct process involved an exceedingly facile and diastereoselective boron trifluoride diethyl etherate-promoted triple electrophilic
[反应:请参见文本] C(3)对称且具有生物活性的天然产物(-)-木酮缩醛A的第一个全合成反应是由间苯三酚(1,3,5-三羟基苯)和( 4R)-3-羟甲基-2,4-二甲基-4,5-二氢呋喃。该非常直接的过程涉及极其容易且非对映选择性的三氟化硼二乙基醚化物促进的三亲电子芳族取代反应,该反应与三个双环缩醛形成反应偶联。
