Nickel-Catalyzed Carboxylation of Conjugated Dienes with Carbon Dioxide and DIBAL-H for the Synthesis of β,γ-Unsaturated Carboxylic Acids

Abstract

Conjugated dienes underwent Ni-catalyst-promoted 1,2-hydrocarboxylation in a 1:1 ratio with carbon dioxide under atmospheric pressure in the presence of diisobutylaluminum hydride (DIBAL-H) to give the corresponding β,γ-unsaturated carboxylic acids, without dimerization or oligomerization of the conjugated diene.

Key words

nickel catalysis - carbon dioxide - dienes - hydrocarboxylation - diisobutylaluminum hydride - alkenoic acids

Anhyd hexane (2 mL), myrcene (540 mg, 4.0 mmol), and a 19% solution of DIBAL-H in hexane (1 mL, 1 mmol) were added under a constant flow of CO₂. The mixture was stirred at rt for 24 h, then 2 M aq NaOH was added and the mixture was diluted with H₂O and extracted with EtOAc (×3). The aqueous phases were then neutralized with 2 M aq HCl and extracted with EtOAc (×3). The combined organic phases were washed with brine, dried (MgSO₄), filtered, and concentrated under reduced pressure. The residual oil was placed in a Kugelrohr (30 Torr, 90 °C) to remove the isovaleric acid byproduct. A 5:1 mixture of 2a and 3a was obtained in the last bulb as a yellow liquid; yield: 0.13 g (70%). 2a ¹H NMR (400 MHz, benzene-d ₆): δ = 5.09–5.15 (m, 1 H). 4.99 (s, 1 H), 4.88 (s, 1 H), 3.01 (q, J = 7.0 Hz, 1 H), 2.12 (m, 4 H), 1.03 (s, 3 H), 1.51 (s, 3 H), 1.15 (d, J = 6.8 Hz, 3 H). ¹³C NMR (100 MHz, CDCl₃): δ = 181.14, 147.45, 131.94, 123.67, 111.46, 45.57, 34.64, 26.30, 25.64, 17.66, 16.05. 3a IR (neat): 3100, 2860, 2638, 1711, 1645, 1454, 1414, 1286, 1231, 1092, 901, 833 cm^–1. ¹H NMR (400 MHz, benzene-d ₆): δ = 6.04 (dd, J = 17.6, 10.8 Hz, 1 H), 5.09–5.15 (m, 1 H), 5.02 (d, J = 17.6 Hz, 1 H), 4.98 (d, J = 10.8 Hz, 1 H), 2.00 (q, J = 8.2 Hz, 2 H), 1.76–1.83 (m, 1 H), 1.60–1.67 (m, 1 H), 1.63 (s, 3 H), 1.51 (s, 3 H), 1.23 (s, 3 H). ¹³C (100 MHz, CDCl₃): δ = 182.64, 140.94, 132.09, 123.62, 114.09, 48.33, 38.95, 25.60, 23.26, 20.16, 17.55.
