When 1-hydroxyethylferrocene, (±)-1, and 1-hydroxy[3](1,1′) ferrocenophane, (±)-4, was used as substrate diisopropyl ether was a suitable solvent. In the reaction conditions investigated, the use of vinyl acetate in diisopropyl ether gave the best yield of (R)-1a (49%, 99% ee) after 2 h of incubation at 30 °C. But, with the amino ferrocenes, 1-amonoethylferrocene, (±)-2, and 1-amono[3](1,1′) ferrocenophane, (±)-5, as substrate, diisopropyl ether was unsuitable as a solvent owing to the low solubility of the substrate in this solvent. Using tetrahydrofuran as a solvent, enzymatic amidation of 1-amonoethylferrocene, (±)-2, gave the best yield of (R)-2a (21%, 99% ee) after 120 h of incubation at 30 °C. CAL working in organic solvent is able to efficiently carry out the resolution of ferrocenyl alcohol and amine derivatives which have similar structures, such as (±)-1 and (±)-2, (±)-4 and (±)-5 which possess central chirality. This enzyme accepted only non-bulky primary alcohols and amines as ferrocenyl substrates. © 1999 Society of Chemical Industry Citing Literature Volume74, Issue6June 1999Pages 501-508 RelatedInformation
