Hydroxy-4-methyl-4-penten-2-one (1) was prepared from 3-chloro-mesityl oxide using a modified procedure from the literature [ref.4], A reference sample of 4-methyl-4-penten-2,3-dione (2) was prepared from using the copper acetate method [ref.2], 4-methyl-pentan-2,3-dione (3) was purchased from Wiley Co. 2-Hydroxy-4-methyl-4-penten-3-one (4) was synthesized in 30% yield from 2-propenyl-magnesium bromide and 2-hydroxy-propionitrile in tetrahydrofurane. The structures of all compounds were confirmed by H-. C-NMR- and mass spectroscopy [ref. 5],... [Pg.414]

The 5-chloro-2-(2-methyl-2-propenyloxy)benzoic acid, methyl ester was heated at reflux for 6 h in l-methyl-2-pyrrolidinone. The mixture was then vacuum distilled and the fraction collected and the desired 2-hydroxy-5-chloro-3-(2-methyl-2-propenyl)benzoic acid, methyl ester was obtained. [Pg.3522]

An example, developed by our group, has been presented 3-chloro-propenyl pivalate, the new synthon we propose as a formal a-hydroxy allyl anion, and chromium(II) chemistry allow to achieve the formal diastereo- and enantio-selective a-hydroxyallylation of carbonyl compounds by applying a catalytic cycle based on an in situ produced Salen-chromium complex (Table 8.3).
