摘要：
The C1-C15 spiroquinolizidine subunit (cf. 2) of the marine natural product halichlorine (1) was prepared in 12 steps starting from the known 'Meyers-lactam' 5. The synthesis involves a B-alkyl-Suzuki coupling followed by a highly stereoselective intramolecular Michael addition and an intramolecular Mannich ring closure. (C) 1999 Elsevier Science Ltd.
