  Synthesis of Symmetrical 2,2',4,4'-Tetrasubstituted [4,4'-Bithiazole]-5,5'(4H,4'H)-diones and Their Reactions with Some Nucleophiles.

  摘要：

  Symmetrical 2,2',4,4'-tetrasubstituted-[4,4'-bithiazole]-5,5'(4H,4'H)-diones were obtained in high yields by oxidation of 5(4H)-thiazolones by KMnO4 in acetic acid. In some cases, the isomeric 2.4'- and 2,2'-bithiazolones were also formed. Results from two crossover reactions were consistent with a free radical mechanism. Four series of thiazolones were prepared, each based on a different substituent at the 2-position; i.e., phenyl, ethoxy, ethyl and ethylthio. The effects of substituents on the isomer distributions of the dehydrodimers indicated that electronic factors were less important than steric factors. X-Ray crystallography established the structure of the dehydrodimer (4R*,4'R*)-2,2'-diethoxy-4,4'dibenzyl-[4,4'-bithiazole]-5,5'(4H,4'H)-dione. One stereoisomer of 2,2'diphenyl-4,4'-dimethyl-[4,4'-bithiazole]-5,5'(4H,4'H)-dione and a mixture of the stereoisomers of 2,2'-diphenyl-4,4'-dibenzyl-[4,4'-bithiazole]-5,5'(4H,4'K)-dione were treated with nucleophiles. The former gave imide derivatives of alpha,alpha'-dehydrodimeric amino acids when the nucleophile was L-alanine ethyl ester or I-butylamine. The structure of one of the reaction products, (4R*,5R*)-2,5-diphenyl-2-thiazoline-4-carboxylic acid piperidylamide, was established by X-ray crystallography. Treatment of stereoisomeric mixtures of 2,2'-diethoxy-4,4'-bithiazolones with HCl in benzene gave the corresponding racemic and meso bis-(N-carboxythioanhydride)s. A stereoisomeric mixture of the bis(N-carboxythioanhydride)s of leucine treated with glycine ethyl ester gave a bicyclic derivative of the alpha,alpha'-dehydrodimeric amino acid.

  Asymmetric alkynylation of thiazolones and azlactones with alkynylbenziodoxolones as the electrophilic alkyne source catalyzed by thiourea phosphonium salt is described. By using thiazolones as nucleophiles, the desired alkyne functionalized thiazolones were obtained in 55–89% yields with 31–86% ee. Azlactones gave the desired products in comparable yields with lower enantioselectivities. Ring-opening

  Photooxidation of several mesoionic compounds gave ring cleavage products, some of which were apparently formed via the endoperoxides of the mesoionic rings. Photooxidation of a Δ2-oxazolin-4-one and a Δ2-thiazolin-4-one gave the corresponding 4,4′-bisoxa- and bisthiazolinone in dichloromethane, whereas the former gave benzamide in dimethylformamide.

  4-substituted 2-phenylthiazol-5(4H)-one and an electron-deficient alkene is shown to include a stable cycloadduct and a Michael adduct formed through the 2- or the 4-position of the thiazolone. The reaction can be diverted towards the Michael adduct entirely, by adding traces of aqueous alkali to the reactants in acetone solution. A novel type of 1:2-adduct is present in the reaction mixture, and is shown to
