The synthesis and examination of two unique classes of duocarmycin SA analogs are described which we refer to as reversed and sandwiched analogs. Their examination established both the origin of the DNA alkylation selectivity and that both enantiomer

The examination of shortened, simplified, and extended analogs of duocarmycin SA is described and constitutes a detailed study of the role of linked DNA binding subunit. In addition to enhancing the DNA binding affinity and selectivity through minor

The preparation and examination of 4–7 revealed that (+)- 5 and (+)-duocarmycin SA were indistinguishable. In contrast, 6 and 7 exhibited properties more analogous to 4 illustrating that the C6 and C7 methoxy substituents of duocarmycin SA contribu

The novel aminobenzindolone 8 was prepared and evaluated as a potential antipsychotic agent. The target compound was synthesized in eight steps starting from the tetrahydrobenzindolone 9. The key step of the synthesis was an electrophilic amination o

An effective synthesis of β-aminotetralins ( 6 ) including an asymmetric electrophilic amination by di-t-butyl azodicarboxylate is reported. Depending on the chiral auxiliaries (S) - 7a-d , the central intermediates 9 and 10 could be isolated in 62

A mild and efficient method for the construction of β-aryl amines from the corresponding α-aryl ketones is presented. The key steps of the synthesis involve an electrophilic amination by dibenzyl azodicarboxylate followed by a stereoselective LiHBE

We have recently communicated the synthesis of the tricyclic lactam 1, which is currently being investigated for its activity as an atypical neuroleptic, from the commercially available tetrahydrobenzindolinone 3a (Scheme 1).7 During this synthesis,
