Total Synthesis of (±)-Spirobenzofuran

Abstract

Spirobenzofuran, embracing a cyclopentane-spirofused benzofuran carbon framework, was efficiently assembled via semipinacol rearrangement with Me₃Al from 2,5-dimethoxy-4-methylacetophenone.

Key words

spirobenzofuran - semipinacol rearrangement - trimethylaluminium - total synthesis - sesquiterpenoid

• 18 Synthesis of Aldehyde 5 To a solution of compound 6 (200 mg, 0.59 mmol) in CH₂Cl₂ (10 mL) was added Me₃Al (0.59 mL, 1.18 mol, 2.0 M in toluene) dropwise at –10 °C under argon. The reaction was warmed to r.t. slowly and stirred for 4 h. Then it was quenched with sat. aq NaHCO₃ (2 mL) at 0 °C. Sat. aq sodium potassium tartrate (10 mL) was added, and the biphasic mixture was stirred overnight. The aqueous layer was separated and extracted with CH₂Cl₂ (3 × 5 mL). The residue was purified by flash chromatography (silica gel, PE–EtOAc = 10:1) to give compound 5 as a yellow solid (176 mg, 88%).¹H NMR (400 MHz, CDCl₃): δ = 9.87 (s, 1 H), 6.92 (s, 1 H), 6.69 (s, 1 H), 3.93–3.88 (m, 4 H), 3.79 (s, 3 H), 3.67 (s, 3 H), 2.77 (d, J = 15.2 Hz, A of AB, 1 H), 2.31 (d, J = 15.2 Hz, B of AB, 1 H), 2.27 (d, J = 14.0 Hz, A′ of A′B′, 1 H), 2.20 (s, 3 H), 1.99 (d, J = 13.6 Hz, B′of A′B′, 1 H), 1.27 (s, 3 H), 0.83 (s, 3 H). ¹³C NMR (100 MHz, CDCl₃): δ = 201.8, 151.8, 150.7, 127.0, 125.8, 114.8, 114.8, 112.3, 64.3, 64.3, 63.3, 56.3, 55.9, 51.9, 44.2, 43.8, 27.0, 23.9, 16.2.
