摘要

1, 2-Indanedione reacts with two equivalents of 2-mercaptoethanol to produce, instead of the expected 1, 2-bis (1, 3-oxathiolane), a dioxa-dithia [4.4. 3] propellane. Other 1, 2- indanediones produce analogous compounds. The protecting groups are removed at room temperature with NBS in aqueous acetone, to produce the original diketone.
