An efficient synthetic route to 1,3,6-trisubstituted azulenes based on the 1-acyloxyazulene scaffold was developed. The 1-position in azulene was substituted in the ring-formation step with a functionalized acyloxy group. Additionally, the 3- and 6-positions of azulene were functionalized with versatile synthetic handles, a halogen atom and a formyl group.
开发了一种基于 1-acyloxyazulene 支架的 1,3,6-三取代的 azulenes 的有效合成路线。在成环步骤中,用官能化酰氧基取代了薁中的 1-位。此外,芘的 3 位和 6 位被多功能合成手柄、卤素原子和甲酰基官能化。
