Ar. Katritzky et al., SYNTHESIS OF PRIMARY AMINES VIA NUCLEOPHILIC-ADDITION OF ORGANOMETALLIC REAGENTS TO ALDIMINES ON SOLID SUPPORT, Tetrahedron letters, 38(40), 1997, pp. 7011-7014
Resin-immobilized aldimines 5, derived from the condensation of amine-
functionalized Rink polystyrene resin with aldehydes, react with Grign
ard reagents, lithium reagents or LiBH4 to afford a wide variety of pr
imary amines in good to excellent yields upon trifluoroacetic acid cle
avage. In this amine synthesis, Rink resin functions both as a solid s
upport and as a NH protecting group. (C) 1997 Elsevier Science Ltd.
