Abstract
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.
