Abstract
Rasta resin-TBD (RR-TBD) was found to be an efficient organocatalyst for γ-selective Morita–Baylis–Hillman reactions between α,γ-disubstituted allenones and aryl aldehydes. In these reactions the heterogeneous nature of RR-TBD greatly facilitated product isolation since the catalyst could be separated simply by filtration.

- 14 General Procedure for the Synthesis of Allenones 3A–D: α-Bromo ketone 4A or 4B (20.0 mmol), Ph3P (6.29 g, 24.0 mmol), and benzene (100 mL) were added to a 250-mL round-bottomed flask equipped with a magnetic stirrer and a condenser. The reaction flask was immersed in an oil bath, and the reaction mixture was refluxed for 2 d. After cooling to r.t., the solvent was removed under reduced pressure to afford the crude phosphonium salt 5A or 5B as a viscous oil. The crude salt dissolved in CHCl3 (65 mL) was transferred to a 100-mL round-bottomed flask equipped with a magnetic stirrer. The reaction mixture was cooled to 0 °C with an ice-water bath and then Et3N (6.1 mL, 44 mmol) was added dropwise. The ice-water bath was removed, and the reaction mixture was then stirred at r.t. for 3 h. The reaction mixture was cooled to 0 °C and the appropriate acid chloride (18.0 mmol) was added dropwise. After 1 h, the reaction mixture was warmed to r.t. and stirred for a further 10 h. The reaction mixture was transferred to a separation funnel and H2O (100 mL) was added. The organic layer was separated and washed with brine (50 mL) and then dried over MgSO4. The solvent was removed under reduced pressure to afford a yellow oil which was then purified by silica gel column chromatography using a mixture of CH2Cl2 and hexane as the eluent. 4-Methylhepta-4,5-dien-3-one (3A): 1H NMR (400 MHz, CDCl3): δ = 5.43–5.50 (m, 1 H), 2.59–2.71 (m, 2 H), 1.79 (d, J = 7.3 Hz, 3 H), 1.76 (d, J = 2.7 Hz, 3 H), 1.07 (t, J = 7.3 Hz, 3 H). 13C NMR (101 MHz, CDCl3): δ = 212.29, 202.88, 159.50, 138.13, 91.70, 88.92, 32.10, 13.49, 13.39, 8.99. HRMS: m/z calcd for C8H12O: 124.0883; found: 124.0881.
- 15 General Procedure for the MBH Reactions: Allenone 3A–D (0.8 mmol), aldehyde 6a–e (0.4 mmol), NMP (1.0 mL), and 1, 2 or 8 (0.08 mmol) were added to a 10-mL round-bottomed flask equipped with a magnetic stirrer. The reaction mixture was stirred either at r.t. (when 1 was used as the catalyst) or at 50 °C (when 2 or 8 was used as the catalyst) for the reaction times indicated in Table 2. When 1 was used as the catalyst, solid NH4Cl (0.006 g, 0.1 mmol) was added to the reaction mixture to quench the reaction. The reaction mixture was then transferred to a separation funnel, and then H2O (30 mL) and EtOAc (15 mL) were added. The organic layer was separated, washed with brine (30 mL), and dried over MgSO4. The solvent was evaporated under reduced pressure to afford an oil, which was purified by silica gel column chromatography using a mixture of EtOAc and hexane as the eluent. When 2 was used as the catalyst, the reaction mixture was merely filtered, and the crude product was purified by silica gel column chromatography. 7-(4-Chlorophenyl)-7-hydroxy-4,6-dimethylhepta-4,5-dien-3-one (7Aa): 1H NMR (400 MHz, CDCl3): δ = 7.29–7.37 (m, 4 H, CHAr, major + minor), 5.26 (s, 1 H, CHOH, major), 5.24 (s, 1 H, CHOH, minor), 2.50–2.64 (m, 2 H, COCH 2CH3, major + minor), 2.43 (br s, 1 H, OH, major), 2.37 (s, 1 H, OH, minor), 1.78 [s, 3 H, (CH 3)CCOEt, major + minor], 1.74 [s, 3 H, (CH 3)CCHOH, major + minor], 1.05 (t, J = 7.4 Hz, 3 H, CH2CH 3, major + minor). 13C NMR (major diastereomer, 101 MHz, CDCl3): δ = 208.73 (s, =C=), 202.80 (s, COEt), 140.12 (s, C ArCHOH), 133.73 (s, CArCl), 128.62 (s, CArH), 127.67 (s, CArH), 106.43 (s, CCHOH), 105.04 (s, CCOEt), 74.48 (s, CHOH), 32.43 (s, CH2CH3), 8.92 (s, CH2 CH3). The signals for (CH3)CCHOH and (CH3)CCO (14.43, 14.20, 13.81) were not assigned due to overlapping signals. 13C NMR (minor diastereomer, 101 MHz, CDCl3): δ = 208.67 (s, =C=), 202.86 (s, COEt), 140.09 (s, C ArCHOH), 133.80 (s, CArCl), 128.67 (s, CArH), 127.74 (s, CArH), 106.42 (s, CCHOH), 105.32 (s, CCOEt), 74.39 (s, CHOH), 32.43 (s, CH2CH3), 8.88 (s, CH2 CH3). HRMS: m/z calcd for C15H17Cl1O2: 264.0912; found: 264.0724.
