A variety of functionalized 3,4-benzo-7-hydroxy-2,9-diazabicyclo[3.3.1]non- 7-enes were prepared by one-pot cyclizations of 1,3-bis(silyl enol ethers) with quinazolines. The mechanism of the cyclization was studied by B3LYP/6-31G(d) density functional theory computations. The products could be functionalized by Suzuki cross-coupling reactions. The reaction of 1,3-bis(silyl enol ethers) with phthalazine afforded open-chain rather than cyclization products. The Royal Society of Chemistry.
Preparation of p-substituted aromatic carbamic acid esters
-
, (2008/06/13)
p-Substituted, aromatic carbamic acid esters are prepared by reacting an aromatic carbamic acid ester with an olefin in the presence of an inorganic acid or sulfonic acid. The aromatic carbamic acid esters obtainable by the process of the invention ar
