Synthetic studies on the ambiguine family of alkaloids: construction of the ABCD ring system
摘要:
A racemic synthesis of the ABCD ring core of the ambiguines that preserves the tertiary alcohol has been accomplished in a convergent synthesis in 10 synthetic steps, in an overall yield of 46% from commercially available 4-bromoindole and m-methylanisole.

The first concise synthesis of marine indole alkaloids (±)-hapalindoles J (4) and M (5) was achieved in seven or six steps starting from a readily available compound 6 using important key reactions, 6 → 7 → and 8 and 35 → 41 or 5.
