Abstract
1,231,380. Isoquinuclidine derivatives. COMMISSARIAT A L'ENERGIE ATOMIQUE. 24 Sept., 1969 [7 Oct., 1968], No. 47063/69. Heading C2C. Isoquinuclidine - (2 - azabicyclo - [2.2.2]- octane) derivatives are prepared by reacting where R, R<SP>1</SP> and R<SP>11</SP> are organic radicals, with ammonia. In examples, piperitenone (R=R<SP>1</SP> = R<SP>11</SP>=CH 3 ) is thus converted to 1,3,3-trimethyl- 2 - azabicyclo - [2.2.2] - octan - 5 - one (I) which is in turn reacted with the acetic anhydride in pyridine to give N-acetyl-1,3,3-trfinethyl-2- azabicyclo-[2.2.2]-octan-5-one and the compound of formula and with LiAlH 4 to give 1,3,3-trimethyl-2- azabicyclo - (2.2.2) - octan - 5 - ol (III). Compounds (I) and (III) are converted to the corresponding nitroxide free radicals by means of H 2 O 2 /phosphotungstic acid.
