  • 새로운 다섯개의 tetrahydroquinazolines 의 합성과 구조 결정 및 생물학적 평가는 보고 되었다. 최초에 준비된 cyclohexanones는 목표분자를 얻기 위한 synthon으로 사용되어졌다. 이들은 치환된 벤즈알데히드와 결합되어졌고, 얻어진 chalcone은 구아니딘 염산염으로 처리했다. 모든 분자들은 인간세포에 무독하며 상당한 항균성을 보여줬다.

  • 8-Oxyquinoline dihydroboronite is prepared by mixing equimolar amounts of 8-hydroxyquinoline and borane-dimethyl sulfide complex in tetrahydrofuran at room temperature and its structure is determined by spectroscopic methods. The reagent is shown to be an extremely mild reducing agent and reduces aldehydes, cyclohexanones, and acid chlorides to some extent. The reagent in the presence of 0.1 equiv of boron trifluoride etherate in tetrahydrofuran at room temperature reduces selectively aldehydes in the presence of ketones, while the reagent in the presence of 1 equiv of boron trifluoride etherate rapidly reduces simple aldehydes and ketones but does not reduce carboxylic acids, esters, and amides.
