Total synthesis of ecteinascidin 743

A convergent total synthesis of ecteinascidin 743 is realized from five building blocks of almost equal size. It takes 23 steps from l-3-hydroxy-4-methoxy-5-methyl phenylalanol (5) with an overall yield of 3%. Copyright

Intermediate and process of preparation of ecteinascidin using such intermediate

The present invention concerns an intermediate of the following formula I in which R1 and R2 represent independently of each other a C1-C12 alkyl group, a (C1-C12 alkoxy)carbonyl group, opt
