Terminal olefins (13), obtained from reactions of tertiary chlorides (10) with triphenylmethyl-lithium, were converted into epoxides (14); base-induced ring-closure of the latter gave 2-hydroxymethyl-2-methylchromans (15) and 3-hydroxy-2,3,4,5-tetrahydro-3-methylbenzoxepins (17).Dehydration of the tetrahydrobenzoxepin (17a) furnished dihydrobenzoxepins.
