Addition of lithium bis(methylenecyclopropyl) cuprate to α,β-unsaturated ketones provides an efficient route to methylenecyclopropyl ketones which on treatment with TiCl4 give a range of cyclised products.

The Lewis acid mediated cyclisation of various methylenecyclopropyl ketones, ketals and aldehydes has been investigated as a new route to six- and seven-membered rings. Cyclisation of aldehyde 6, ketal 9 and ketone 11 with TiCl4 gave cyclohexen
