A modular and practical route to versatile cyano-1,3-dienes by a sequence involving deconjugative alkylation and “Tsuji–Saegusa–Ito oxidation” is reported. In this letter, the versatility of the products is also explored, including a route to benzochromene scaffolds common to many natural products.
据报道,通过涉及去共轭烷基化和“ Tsuji–Saegusa–Ito氧化”的序列,一种模块化实用的途径可用于制备多功能氰基1,3-二烯。在这封信中,还探讨了产品的多功能性,包括一条通往许多天然产品常见的苯并二氢萘骨架的途径。
