The first stereocontrolled synthesis of the title δ-aminoboronic esters—proceeding from commercially available nitriles—via a reduction, Brown’s ‘allyl’ boration reaction, a Boc-protection, a hydroboration, an oxidative elimination of α-pinene, and an esterification reaction, has been reported in excellent enantio- and diastereoselectivities.
通过还原,布朗的“烯丙基”硼酸化反应,Boc保护,氢硼化,α-pine烯的氧化消除和酯化反应,由市售的腈类化合物首次立体合成标题的δ-氨基硼酸酯。已经报道了优异的对映异构和非对映异构选择性。
