✦ Synopsis

The condensation of alkyl-substituted thermodynamic enolates with ethyl bromomagnesium cyclopropanone hemiacetal (a cyclopropanone equivalent) provides l-(2-ketoalkyl) cyclopropanols which in turn are converted into 3-hydroxycyclopentanones by treatment with base.

1,2-Indanedione reacts with two equivalents of 2-mercaptoethanol to produce, instead of the expected 1,2-bis(1,3oxathiolane), 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 pr
