Industrial methods[ edit ] Alkenes are produced by hydrocarbon cracking. Raw materials are mostly natural gas condensate components principally ethane and propane in the US and Mideast and naphtha in Europe and Asia. Alkanes are broken apart at high temperatures, often in the presence of a zeolite catalyst, to produce a mixture of primarily aliphatic alkenes and lower molecular weight alkanes. The mixture is feedstock and temperature dependent, and separated by fractional distillation.

The general strategy for the asymmetric construction of the required dienes is illustrated in Scheme 2 for the preparation of cyclic ether Treatment of 3-butenol with sodium hydride and bromoacetic acid in THF.

Asymmetric olefin metathesis does not seem possible at first glance, because no sp3-hybridized carbons are formed during a metathesis reaction. Instead of creating a new sp3 carbon, asymmetric metathesis reactions form chiral compounds through either.
