この論文ではP450 biocatalyst CreJ を中心とする新しいchemomimetic biocatalytic systemを構築したということが報告されています。この反応系を用いてアルキルフェノールのC-H結合のregioselectiveな酸化が達成されています。水酸基によって反応場での位置が固定されて選択性が表れているのですが、そもそも基質に導入してある水酸基はBDEが低いために、「アルキルのC-H結合とのregioselectivity」ということもポイントにできている点は面白いと思いました。要するに水酸基が「基質の固定」と「アルキルC-Hへのregioselectivityを強調する反応点」の役割を果たしているという点です。
基質の位置の固定
僕の反応系でも疎水性反応場なので、あえて水酸基を持つ基質を用いることでregiselectivityが生まれることが期待出来るかもしれないと考えています。
