The first total synthesis of the pro-resolving and tissue-regenerative resolvin sulfido-conjugates: 7S,8R,17S-RCTR1, 7S,8R,17S-RCTR2 and 7S,8R,17S-RCTR3, derived from docosahexaenoic acid, has been achieved. Two synthetic approaches are described. Chiral centers 7S and 8R were introduced in both approaches via a chiral pool strategy starting from 2-deoxy-D-ribose. The 17S chiral center was
