Formation of deaminated products in styrene oxide reactions with deoxycytidine.

The reaction of racemic styrene oxide with deoxycytidine under aqueous conditions was studied. The four principal products isolated were a pair of diastereomeric N(4)-(2-hydroxy-1-phenylethyl)deoxycytidines ( approximately 20% of the products) and a pair of diastereomeric 3-(2-hydroxy-2-phenylethyl)deoxyuridines ( approximately 80% of the products). Reactions with optically active styrene oxides allowed the configurations of the 3-(2-hydroxy-2-phenylethyl)deoxyuridines to be assigned, and these structures were confirmed by an independent synthesis from deoxyuridine. Also, it was possible to tentatively assign the configurations of the N(4)-(2-hydroxy-1-phenylethyl)deoxycytidines that had undergone some racemization during the reaction (the ratio of the retained to inverted configuration of the products was approximately 1:7).
