Abstract

Conjugate addition of Boc-L-Cys-OH to 3-methylcrotonaldehyde, in situ reduction with sodium borohydride, and in situ deprotection with hydrochloric acid, directly followed by chromatography gives L-felinine in 73% yield. Similar syntheses may produce acid building blocks for combinatorial libraries.
