Palladium-catalyzed oxidative cyclization of alkenols provides a convenient entry into cyclic ethers but typically proceeds with little or no diastereoselectivity for cyclization of trisubstituted olefins to form tetrahydrofurans due to the similar energi

CpCr(CO)3H and HV(CO)4(P-P) (where P-P is a chelating diphosphine) can be used to initiate radical cyclizations by transferring H{radical dot} to activated terminal olefins. CpCr(CO)3H can catalyze reductive cyclizations,
Substituent control in the synthesis of tetrahydropyrans, oxepanes and oxocanes by episulphonium ion-mediated cyclisation
Lopez-Tudanca,Jones,Brownbridge
, p. 2261 - 2264 (2007/10/02)
Cyclisation of the heptenols (1), (6a), (6b), and (6c) to cyclic ethers via episulphonium ions has been studied and the effect of allylic substituents on the size of ring produced has been explored.
