The lithio-derivative undergoes Peterson-type olefination (see Appendix 4) with aldehydes and ketones to give the ketene dithioacetals, useful intermediates in a variety of reactions: J. Org. Chem., 37, 1926 (1972); J. Chem. Soc., Perkin 1, 2272 (1973); Chem. Ber., 106, 2277 (1973). Further reaction with carbonyl compounds provides, after deprotection, a useful -lactone synthesis. An alternative PhSeCl-promoted ring closure, followed by selenoxide elimination gives the butenolide: J. Org. Chem., 45, 2236 (1980):

Tandem bis-alkylation with epoxides provides a route to enantiopure 1,5-diols and related compounds; the key step is a [1,4] Brook rearrangement of the initially-formed alkoxide: Synlett, 511 (1994):
