An iron(II)-mediated aminohalogenation of a cyclopentenyl N-tosyloxycarbamate provided new access to the key intermediate for the synthesis of (−)-agelastatin A (AA, 1), a potent antiproliferative alkaloid. The present synthetic endeavour offered a

A new synthetic route to clavilactone B, a naturally occurring inhibitor of epidermal growth factor receptor (EGFR) tyrosine kinase, is disclosed. The route features a sequential samarium-mediated radical cyclization–fragmentation of an indanone de

(−)-Agelastatin A (AA), isolated from the coral sea axinellid sponge Agelas dendromorpha, has shown a high antineoplastic activity. We have synthesized eighteen AA analogues and analyzed their cytotoxicities towards three cancer cell lines. By the
