Cells of Mycobacterium alvei are known to contain a unique set of mycolic acids with a (ω-1)-methoxy group; although the various enzymes in the biosynthesis of other types of mycolic acid have been widely studied, the biosynthetic route to this subs

The dichloro- and dibromocarbene adducts of chloroprene and 2,3-dichlorobutadiene are readily dehalogenated by reaction with methyllithium to give 1-halo-2-vinylcyclopropenes which on further lithium-halogen exchange give synthetically useful 1-lithi
