to mask phenol and arylacetaldehyde moieties simultaneously in the synthesis of analogues of mycophenolic acid (MPA) was explored. Benzofuran 4 provided a stable and easily handled intermediate for the preparation of unnatural derivatives at the C-6 position of MPA. Preparation of the highly potent 6-ethyl MPA analogue 2 was accomplished via aldehyde 2c through this facile route with high-yielding
探索了在合成麦考酚酸(MPA)类似物中使用苯并呋喃同时掩蔽苯酚和芳基乙醛部分的方法。苯并呋喃4提供了稳定且易于处理的中间体,用于制备MPA C-6位置的非天然衍生物。通过醛2c,通过具有高产率的步骤和结晶中间体的该容易路线,完成了高效6-乙基MPA类似物2的制备。
