scheme or table, p. 2969 - 2975 (2010/11/05)
A novel protocol for intramolecular ketyl-olefin radical cyclization with low-valent titanium reagent is outlined. It allows the formation of the benzopyran nucleus from ortho-allyloxy propiophenones as the sole product in moderate yields via intramolecular radical cyclization.

The effect of variation of the rigid part of the parent Cram hemispherand 1a on the preorganization of the macrocyclic cavity has been studied.Four novel 18-membered hemispherands (3,4a-c)have been synthesized via a novel multistep route using 2,6-di- and
