Peterson-olehnation

A variety of methylenecyclopropanes have been prepared by the Peterson olehnation procedures (equations 137,138) 1-Alkylcyclopropyl selenides give alkylidene-... [Pg.355]

Following these examples, methylene cyclopropene and certain 5,6-dihydrocali-cenes are now obtainable. Adding lithio trimethylsilylcyclopropanes to aldehydes also provides alkylidene cyclopropanes (Peterson olehnation route) . An approach to a-methylene y-butyrolactones starting with dibromocyclopropanes has been opened by a suitable manipulation of intermediate cyclopropyl anions (equation 133). ... [Pg.414]
