For the construction of chiral monofluorinated tertiary carbons, we have examined the asymmetric Diels–Alder reaction of 2-fluoroacrylic acid derivatives bearing a chiral oxazolidinone moiety. Under diethylaluminum chloride catalyzed conditions at −100°C, the reaction of 1 with isoprene proceeded smoothly with high diastereoselectivity.
对于手性单氟化叔碳的构造,我们研究了带有手性恶唑烷酮部分的2-氟丙烯酸衍生物的不对称Diels-Alder反应。在-100℃下在二乙基氯化铝催化的条件下,1与异戊二烯的反应顺利进行,具有高非对映选择性。
