The crystal structure of 1,3—dimethyl-6-azathymine and its four photocycloadducts of CH_2CH-Z(Z=CN, COCH_3) were determined by X-Ray diffraction. The main crystallographic data are listed in Tabie 1. The absolute configurations of the compounds(Ⅱ) and (Ⅳ) were not determined.
The molecular structure of 1,3-dimethy-6-azathymine is shown in Fig.1. Its six-membered ring is roughly planar. The C-N single bond lengths which are nearly equivalent in the six-membered ring are shorter than that in the photocycloadducts (see ...
