Intended syntheses of cyclopentane counter-pyrolytic decarboxylation gave not the expected 3-parts of deoxyribonucleosideslr2 as possible anti-cyclopentene-1-carboxylic acid (IX), but an isocancer agents required the availability of 3-cyclo-meric, neutral substance. Infrared data suggested penten-1-ylamine (XVI). A likely precursor for the presence of vinyl-and y-lactone functions. A this amine is diethyl 3-cyclopentene-l, l- ...
