Description

Ecteinascidin 743 (ET 743) is an extremely potent antitumor agent isolated from a marine tunicate, Ecteinascida turbinate. ET 743 is currently undergoing phase II/III clinical trials in Europe and the United States. The novel structural features, poor availability from the natural sources, and the unique mechanism of action have made ET 743 a very attractive target for synthetic chemists. To date, total syntheses have been completed by Corey, Danishefsky, Zhu, and ourselves. We report herein a formal total synthesis of ET 743, featuring a regio- and stereoselective Pictet-Spengler reaction to afford the tetahydroisoquinoline and a diastereoselective Mannich-type reaction of the iminolactone. We have succeeded in the efficient construction of the bicyclo[3.3.1] skeleton from the Mannich-type reaction product.
