- Tandem reactions leading to benzo[c]chromen-6-ones and 3-substituted isocoumarins
-
A simple and convenient protocol for the synthesis of benzo[c]chromen-6- ones and 3-substituted isocoumarins through a CuI-catalyzed tandem reaction of 2-bromobenzoates withcyclohexane-1,3-diones or acyclic 1,3-diones is developed. This strategy can also be extended to the one-pot synthesis of isoquinolin-1(2H)-one and 3,4-dihydrophenanthridine-1,6(2H,5H)-dione. A simple and convenient protocol for the synthesis of benzo[c]chromen-6-ones and 3-substituted isocoumarins through a CuI-catalyzed tandem reaction of 2-bromobenzoates with cyclohexane-1,3-dione or acyclic 1,3-dione has been developed. This strategy can also be extended to the one-pot synthesis of isoquionlin-1(2H)-one and 3,4-dihydrophenanthridine-1,6-(2H,5H)-dione. Copyright

- Revisiting [3 + 3] route to 1,3-cyclohexanedione frameworks: Hidden aspect of thermodynamically controlled enolates
-
We have revisited the traditional consecutive Michael-Claisen [3 + 3] process (MC-[3+3]) promising the synthesis of a cyclohexane-1,3-dione derivatives from nonactivated simple ketones and enoates and evaluated its potential in modern organic synthesis. Twenty to thirty examples were demonstrated to be effective. The reactions exhibited remarkable regioselectivity with the Michael addition proceeding through nucleophilic attack by the more hindered site of the ketones without exception. The subsequent Claisen condensation resulted in the formation of carbon-carbon bonds between less hindered site of the ketones and acyl carbon of the enoates. The MC-[3+3] process described is useful for the synthesis of Taxol A-ring synthons in multigram quantities and for the synthesis of other six-membered carbocyclic compounds. A number of control experiments have been conducted to provide strong support for the mechanism of this MC-[3+3].
