The C11-N26 fragment of griseoviridin has been prepared enantioselectively. The 1,3-syn diol synthon was derived from lipase-catalyzed selective acylation of(±)-1-(benzyloxy)pent-4-en-2-ol. The conjugated (E,E)-dienylmethyl azide functionality was installed by a Pd-catalyzed allylic azidation reaction.
灰黄霉素异丁烯的C11-N26片段已经对映选择性地制备。1,3-syn二醇合成子衍生自脂肪酶催化的(±)-1-(苄氧基)pent-4-en-2-ol的选择性酰化反应。通过Pd催化的烯丙基叠氮化反应来安装共轭的(E,E)-二烯基甲基叠氮化物官能度。
