Diethyl mesaconate

Radical additions of primary, secondary, and tertiary alkyl bromides 249 to diethyl mesaconate 248 catalyzed by 5 mol% vitamin B12a 247 (X=OH2) proceeded in yields of 63-90% [301]. Deuteration experiments and comparison to similar addition processes support that 247 is initially reduced to cobalt complex 253A. This reacts with 249 giving an alkylcobalamin(III) intermediate... [Pg.261]

Stereoselective addition of t-BuBr to a, fi-enoates.2 Reaction of f-BuBr with diethyl mesaconate with reduction by zinc with ultrasound results in syn-1 and anti-1 in the ratio 85 15. Similar stereoselectivity obtains in radical reactions promoted... [Pg.406]
