Highly Selective Syntheses of Coniferyl and Sinapyl Alcohols

Highly Selective Syntheses of Coniferyl and Sinapyl Alcohols

(E)-Isomers of coniferyl and sinapyl alcohols were readily and cleanly prepared in excellent yields from commercially available coniferaldehyde and sinapaldehyde by sodium triacetoxyborohydride reduction in ethyl acetate. No 1,4-reduction products, always produced in prior methods, could be detected...

Zusammenfassung:(E)-Isomers of coniferyl and sinapyl alcohols were readily and cleanly prepared in excellent yields from commercially available coniferaldehyde and sinapaldehyde by sodium triacetoxyborohydride reduction in ethyl acetate. No 1,4-reduction products, always produced in prior methods, could be detected.
