• Studies on the N-oxides of .PI.-deficient N-heteroaromatics. XXXIV. A novel synthesis of substituted indoles by photochemical ring contraction of 3,1-benzoxazepines.

  A novel photochemical ring-contraction reaction of 5-unsubstituted 3, 1-benzoxazepines and their 5-halogeno or carboxyl derivatives to yield 3-formylindoles in an aprotic solvent is reported. This ring contraction was successfully extended to oxazepines having an alkoxycarbonyl function at the 5-position to give the indoles having this function at the 3-position. Though most of the oxazepines underwent the ring-contraction reaction only on irradiation at 254 nm, 5-carboxy derivatives or their esters afforded the ring-contraction products even at ≥ 300 nm. The intermediacy of 3H-indole species in these photochemical ring-contraction reactions was demonstrated by the isolation of methyl 3-acetyl-2-phenyl-3H-indole-3-carboxylate during the photolysis of methyl 4-methyl-2-phenyl-3, 1-benzoxazepine-5-carboxylate. It was found that this 3H-indole afforded methyl 6-and 4-acetyl-2-phenyl-indole-3-carboxylates upon further irradiation. The mechanism of this acetyl migration is discussed based on the result of the photochemical acetyl migration of methyl 1-acetyl-2-phenylindole-3-carboxylate.

  As a basic study on the efficient synthesis of chromogenic and fluorogenic peptidase substrates, we investigated possible general methods for the synthesis of α-amino acid and peptide amides of aromatic amines. Preparation of Boc-L-Leu-pNA (1) as a model compound was attempted by (1) the coupling of Boc-L-Leu-OH with p-nitroaniline, (2) the reaction of Boc-L-Leu OH with p-nitrophenyl isocyanate, and (3) the reaction of Boc-L-Leu-OH with the product formed from p-nitrobenzoic acid through the modified Curtius reaction with diphenyl phosphorazidate ((C6H5O) 2P (O) N3) in a one-pot process. The third method was found to be a general and efficient method for the preparation of α-amino acid amides of aromatic amines. Application of this method to the preparation of a peptidase substrate, Bz-L-Ile-L-Glu (OMe) -Gly-L-Arg-pNA (2), has also been successfully achieved.

  作为染料和荧光素酶底物高效合成的基础研究，我们探索了合成芳香胺类α-氨基酸和肽酰胺的可能通用方法。通过以下三种方法尝试制备模型化合物Boc-L-Leu-pNA (1)：(1) Boc-L-Leu-OH与对硝基苯胺的偶联反应，(2) Boc-L-Leu-OH与对硝基苯基异氰酸酯的反应，以及(3) 在一步法中将Boc-L-Leu-OH与通过二苯基磷酰叠氮((C6H5O) 2P (O) N3)改进的Curtius反应生成的对硝基苯甲酸产物反应。发现第三种方法是制备芳香胺类α-氨基酸酰胺的一种通用且高效的方法。这种方法也已成功应用于制备肽酶底物Bz-L-Ile-L-Glu (OMe) -Gly-L-Arg-pNA (2)。
