  Photochemistry of 4-(2‘-Aminoethyl)quinolones:  Enantioselective Synthesis of Tetracyclic Tetrahydro-1aH-pyrido[4‘,3‘:2,3]- cyclobuta[1,2-c] Quinoline-2,11(3H,8H)-diones by Intra- and Intermolecular [2 + 2]-Photocycloaddition Reactions in Solution

  摘要：

  Enantioselective [2 + 2]-photocycloaddition reactions on 4-(2'-aminoethyl) quinolones in solution were studied using the enantiomerically pure complexing agent 1 as source of chirality. The intermolecular reactions of fully N-protected substrates 5a-5c with different 2-alkyl-substituted acrylates 12-15 represent the first systematic study on the diastereoselectivity of their intermolecular [2 + 2]-photocycloadditions to unsymmetrically 1,1-disubstituted olefins (75-91% yield, d.r. = 58/42-95/5). N-Benzylic-protected photoproducts exo-16a/b-19a/b could easily be converted into lactams 20a/b-23a/b by a sequence of Boc deprotection and thermal lactamization (74-98% yield). Identical products 20a-22a were directly accessible by the intramolecular [ 2 + 2]-photocycloaddition of acrylic acid amides 2-4 (41-61% yield). The suitability of both pathways for an enantioselective reaction variant was proven (70-92% ee). Thus, tetracyclic lactams possessing the carbon framework C were obtained with good yields and enantio-selectivities of up to 92% ee in intramolecular reactions. Comparative investigation of both routes showed that quinolone dimerization was the single most decisive factor preventing a complete chirality transfer. Functional group manipulations were successfully conducted with the primary photoproduct exo-17a. Finally, a new and unexpected type of benzylic hydrogen abstraction-radical cyclization reaction was discovered for substrate 5a, which explains the photochemical instability of substrates 2-5 under short wavelength irradiation (lambda = 300 nm).

  A series of N-acyl amino acid analogues of 2 (1H)-quinolinone was synthesized and tested for antiulcer activity against acetic acid-induced gastric ulcer in rats. These compounds were synthesized by the acylation of amino acid derivatives of 2 (1H)-quinolinone, which were obtained from the reaction of ω-bromoalkyl 2 (1H)-quinolinones and acetamidomalonate in the presence of sodium ethoxide, followed by hydrolysis with diluted hydrochloric acid. Among them, 2-(4-chlorobenzoylamino)-3-[2 (1H)-quinolinon-4-yl] propionic acid (VIIIf) was found to have the most potent activity. The structure-activity relationships are discussed.

  Quinolin-2-ones bearing a heteroaryl-piperazine linked by a two carbon chain at the 3- or 4-position were synthesised and evaluated as mixed 5-HT1B/5-HT2A receptor antagonists. Potent mixed antagonists were obtained with thieno[3,2-c]pyridine derivatives. In this series, compound 2.1 (SL 65.0472) proved to be functional antagonist at both the 5-HT2A receptor (rat in vivo 5-HT-induced hypertension model) and the 5-HT1B receptor (dog in vitro saphenous vein assay).

  Protein kinase C (PKC) isotypes have emerged as key targets for the blockade of early T-cell activation. Herein, we report on the structure - activity relationship and the detailed physicochemical and in vivo pharmacokinetic properties of sotrastaurin (AEB071, 1), a novel maleimide-based PKC inhibitor currently in phase II clinical trials. Most notably, the preferred uptake of sotrastaurin into lymphoid tissues is an important feature, which is likely to contribute to its in vivo efficacy.
