, p. 590 - 603 (2007/10/02)
The synthesis, physicochemical properties, and biological activities of a series of novel spiro cyclopropyl compounds, modeled on the potent antitumor antibiotic CC-1065 (1), are described. Many of these synthetic analogues are significantly more effectiv
Preparation and Stability of 1,4-Oxathian-2-ones
Koskimies, Jorma K.

Several methods of preparation of various substituted 1,4-oxathian-2-ones are described, including the acid-catalyzed ring closure of δ-hydroxy acids, prepared via α-halo ketones or α-halo acids, and the base-catalyzed ring closure of β-haloethyl thioglycolate. 1,4-Oxathian-2-one is completely hydrolyzed in D2O to the hydroxy acid at a rate comparable to the hydrolysis of δ-valerolactone.The rate of the lactonization is estimated to be ca. 100 times smaller in oxathianone than in valerolactone.
