Model studies in the lepadin series: synthesis of enantiopure decahydroquinolines by aminocyclization of 2-(3-aminoalkyl)cyclohexenones
摘要:
Syntheses of enantiopure 3-acetoxy-2-methyldecahydroquinolines are accomplished by coupling cyclohexenyl lithium 3 with alpha-amino epoxides and an aminocyclization of 2-(3-aminoalkyl)cyclohexenones (i.e., 5 and 9) as the key steps. The procedure allows the incorporation of alkyl substituents at C(5) to give enantiopure 2,3,5-trisubstitued decahydroquinolines. (c) 2005 Elsevier Ltd. All rights reserved.
