✦ Synopsis

The 'exo'and 'endo'descriptors

are used to designate the orientation of the cyclopropane ring in the transition states andin the products of the cycloaddition to furans. The use of these descriptors is extended, by analogy, to cycloadditions of cyclopropenes to open-chain dienes [3] [4]. Data were collected on a Philips PW-1100 diffractometer (MoK,). The structure was solved by direct methods (MULTAN 80) [6] and refined by full-matrix least-squares analysis (XRAY 76) [7]. Crystallographic data have been deposited with the
