Wj. Kerr et al., A polymer-supported alkyl methyl sulfide as an efficient promoter of the Khand cyclisation reaction, CHEM COMMUN, (16), 2000, pp. 1467-1468
A readily prepared polymer-supported alkyl methyl sulfide has been shown to
be a recyclable, practically convenient, and efficient promoter of the Kha
nd cyclisation reaction, affording good to excellent yields of cyclopenteno
nes.
