Abstract
|
|
|
|
Novel halactolactonizations using NBS (2), NIS(3), and NSP (4) in dry DMF were found to be the most reasonable and efficient procedures. The participation of X(+) as the cyclization initiator could be clearly rationalized by experimental results and the regioselectivities of formed halolactones were reasonably elucidated by weakly bridged carbonium ion intermediate.
