    摘要: Disclosed is a three step synthesis of 11-aryl-5,6-dihydro-11H-dibenznullb,enullazepines from a 2-aminobenzophenone represented by the following structural formula: 1 and a starting material represented by the following structural formula: 2 ,2 Phenyl Ring A, Phenyl Ring B and Phenyl Ring C are independently unsubstituted or substituted with one, two or three substituents. Each substituent on Phenyl Ring A, Phenyl Ring B and Phenyl Ring C is independently chosen. R is nullH, a aliphatic group, a substituted aliphatic group, an aryl group, a substituted aryl group, nullC(O)nullRnull, nullC(O)nullH, nullC(O)nullNHRnull, nullS(O)2Rnull, nullC(O)nullC(O)nullRnull, nullC(O)nullC(O)nullH, nullC(S)nullRnull, nullC(S)nullH, nullC(O)nullORnull, nullC(S)nullORnull, nullC(O)nullSRnull, nullC(S)nullSRnull, nullC(O)nullNRnull2 or nullC(O)nullC(S)nullRnull. Rnull is an aliphatic group, a substituted aliphatic group, an aryl group or a substituted aryl group. R1 is a leaving group. The present invention also includes novel compounds which are intermediates in the preparation of 11-aryl-5,6-dihydro-11H-dibenznullb,enullazepines.

    摘要: The present invention relates to a method of preparing a 1-nitro-3-substituted-3-amino-2-propanol diastereomer represented by Structural Formula I: 1 In Structural Formula I, R is an amine protecting group, and R1 is an amino acid side-chain, a protected amino acid side-chain, a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aromatic group, a substituted or unsubstituted heteroaromatic group, a substituted or unsubstituted aralkyl or a substituted or unsubstituted heteroaralkyl group. The method involves contacting a 1-nitro-3-substituted-3-amino-2-propanone with a reducing agent to form a mixture of 1-nitro-3-substituted-3-amino-2-propanol diastereomers. The 1-nitro-3-substituted-3-amino-2-propanol diastereomers are then separated by simulated moving bed chromatography to obtain one or more 1-nitro-3-substituted-3-amino-2-propanol diastereomer.
