The remarkable effect of cosolvent on a samarium(II)-mediated 4-exo-trig cyclization: Further synthetic studies on pestalotiopsin A

A samarium(II)-mediated 4-exo-trig cyclization in which a remote stereocenter serves to control the facial selectivity of the cyclization is described. The apparent coordination of a tertbutyldimethylsilyl ether to the samarium center appears to give rise
