Experimental Section
The starting materials MBH bromides were prepared according to the reported method from MBH adducts with aqueous HBr or PBr3.11 Glutaconate derivatives 2a (E) and 2b (E) were prepared by esterification of commercial trans-glutaconic acid. Triethyl aconitate (2c, E) was prepared by esterification of commercial trans-aconitic acid.12
Typical Synthetic Procedure of 3a. A stirred solution of 1a (239 mg, 1.0 mmol), 2a (205 mg, 1.1 mmol), Cs2CO3 (489 mg, 1.5 mmol) in DMF (3.0 mL) was heated to 90 ℃ for 1 h. After the usual aqueous extractive workup and column chromatographic purification process (hexane/ether, 10:1), compound 3a2a was obtained as colorless oil, 235 mg (72%). Other compounds were synthesized similarly, and the spectroscopic data of 3b-i and 4a are as follows.
