Asymmetric synthesis of (R)-[2,2-]-1-aminocyclopropane-1-phosphonic acid (ACPP derivative) conformationally constrained ACC analogue using a chiral sulfinyl auxiliary
摘要:
The asymmetric cyclopropanation of vinylphosphonate using (S)-dimethylsulfonium-(p-tolylsulfinyl)methylide was applied to obtain a dideuterated cyclopropyl sulfoxide. A three-step synthesis of enantiopure (+)-(1R)-1-amino-2,2-dideuteriocyclopropanephosphonic acid (+)-17-d(2) was developed. (C) 2013 Elsevier Ltd. All rights reserved.
