Synthesis of a fluorescent 2'3'-dideoxycytosine analog, tCdd.
The pathway leading to the preparation of a novel tricyclic 2'3'-dideoxycytosine analog, tCdd (1) is reported. A protected 2'3'-dideoxyribose prepared from l-glutamic acid was coupled to a silylated fluorescent base to yield a mixture of the alpha- and beta-anomers of the 2'3'-dideoxyribonucleoside of 1,3-diaza-2-oxophenothiazine, tCdd (1). The fluorescent base analog retains a high fluorescence emission over a large pH range and should be useful in a variety of probe applications.
