Non-Metal Lewis Acid-Catalyzed Cross-Claisen Condensation for β-Keto Esters

In this work, we disclose a new catalytic and high chemoselective cross-Claisen condensation of esters. In the presence of TBSNTf2 as non-metal Lewis acid, various esters can undergo cross-Claisen condensation...

An Efficient Approach for the Synthesis of 1,2-Dihydroxanthones Enabled by One-pot Claisen Condensation/Cyclization Reactions

1,2-Dihydroxanthones (DHXs) are core structures of natural products and useful building blocks in organic synthesis. They have been so far less studied. In this report, a mild, efficient and green...
