Various natural carbohydrate precursors have utility in the synthesis of lamivudine; for example, a synthesis from L-gulose has recently been reported. Emtricitabine : 21 Emtricitabine It is a fluorinated lamivudine ( analog) Orally well absorbed Plasma half life ~ 40 hrs - Once a day dose. This patent describes the preparation of Lamivudine as a mixture of cis and trans isomers (shown in scheme I). A variety of routes are available for preparing chiral oxathiolane intermediates which may be coupled to the cytosine base under appropriate conditions where the chirality of the oxathiolane is maintained. Being in recovery can be very stressful, when there is difficulty, you can come on here, post how you feel, or read the stories of other people that have gone through exactly the same thing and get tips & drive to push through.
