Description générale
Resin-bound p-nitrophenyl carbonate esters react readily with amines to provide the corresponding resin-bound carbamate. Leznoff [1] was the first to demonstrate the utility of such resins in solid phase synthesis with the preparation of mono-acylated diamines from symmetrical diamines. Similarly, Dressman, et al. [2] have used carbamate linked resin-bound amino acid amides to make hydantoins via a base-mediated cyclization/cleavage strategy. Amines linked to p-nitrophenyl carbonate Wang resin possess similar chemical properties to methoxybenzyloxycarbonyl protected amines. The resin-bound carbamate is, therefore, cleaved with TFA or hydrogenolysis to afford the free amine [3]. Alternatively, cleavage by reduction with lithium aluminium hydride can be used to generate N-methylamines [4], and Raju & Kogan [5] have utilized this resin to prepare sulfonamides by acylation of immobilized arylamines and cleavage with LiOH or NaOMe. An analogous p-nitrophenyl carbonate resin prepared from NovaSyn TGA resin was employed as a support for the solid phase immobilization of amidines [6]. This resin was also used to synthesize polyamines [7, 8], and to immobilize indoles [9] and guanidinylating reagents [10]. Loading of this resin can be quantified by measuring the release of p-nitrophenolate [11].
