  Synthesis and properties of atropisomeric phosphinous acids

  摘要：

  In this paper we describe two groups of atropisomeric phosphinous acids-bis-[(N,N-diisopropyl-1-naphthamide)-2-]-phosphinous acids (2 to 4) and their 8-methoxy- substituted relations (8 to 10). The first group of acids interconvert at room temperature and the second group do not. The interconversion and properties are illustrated by two dimensional TLC and some NMR spectra. The peri substituent turns out to be important. (C) 2004 Elsevier Ltd. All rights reserved.

• Synthesis of atropisomeric 2,8-dioxygenated N,N-diisopropyl-1-naphthamides via kinetic resolution under Sharpless asymmetric dihydroxylation conditions

  日期：2004.2

  A kinetic resolution approach under Sharpless asymmetric dihydroxylation conditions was used to synthesize enantio-enriched atropisomeric N,N-diisopropyl-1-naphthamides possessing oxygenated functionalities at both the C2 and C8 positions. A significant influence of the substrate structures on the efficiency of the kinetic resolution was observed. (+)-(aS)-N,N-Diisopropyl-2[2'-(E)-butenoyloxy]-8-methoxy-1-naphthamide is obtained in 35% yield with 94.3% ee after treating the racemate with 3.5 mol% each of Os and (DHQD)(2)-PHAL at 0degreesC for 22 h.

• Perilithiation and the synthesis of 8-substituted-1-naphthamides

  日期：1999.12

  Attempted perilithiation of 1-naphthamides with their 2-positions blocked leads only to nucleophilic attack on the aromatic ring, but perilithiation of naphthalenes bearing l-substituents such as -NMe2 or -CH2NMe2 allows the synthesis of 8-substituted-1-naphthamides. The 8-CH2NMe2 substituents can be converted to carbonyl groups by Polonovski reactions; other 8-substituents may be introduced by using naphthalic anhydride as a starting material.
