addition of a 1,3-dioxan-4-ylcopper(I) reagent to a cationic eta3-allylmolybdenum complex as part of a synthesis of (2E,5S,6R,7E)-6-methyl-8-phenylocta-2,7-dienoic acid, a key component of the Cryptophycins. Oxidative addition of Mo(CO)(4)(THF)(2) to allyl benzoates provides an efficient synthesis of eta3-allylmolybdenum(dicarbonyl) complexes.
通过将1,3-二恶烷-4-基铜(I)试剂亲核加成到阳离子eta3-烯丙基钼络合物中,作为(2E,5S,6R,7E)合成的一部分,构建了两个相邻的立体异构中心和一个侧链烯烃。 -6-甲基-8-苯基辛基-2,7-二烯酸,隐藻霉素的关键成分。Mo(CO)(4)(THF)(2)氧化加成到苯甲酸烯丙酯中,可有效合成eta3-烯丙基钼(二羰基)配合物。
