Isomerization with methyl magnesium derivative

Reaction of methyl quinolinylsulfoxide (86) with allylmagnesium chloride or with 1-methylallyl-magnesium chloride led to the 2-allyl and 2-(l-methylallyl)quinoline, (87) and (88) respectively, contaminated with unseparable isomeric a,p-unsaturated derivatives, in high yields. ... [Pg.62]

In the context of a chemical study related to problems of vitamin B12 biosynthesis, peripheral C-methylation of the magnesium complex of tctct-OEPc (17) was reported to yield a mixture of isomeric products (18a-c) (83AG(E)631). A similar reaction was found to occur at C-12 of nonamethyl pyrrocorphin (19). One of the by-products of this reaction is the seco-corphinoid derivative 20, which, on complexation with Ni(II) acetate, cyclizes to give an Ni(II) corrinate (21) (84CC583). [Pg.89]
