Using the tri-iodide/iodide redox couple and the sensitizers (22) and (56), several groups have reported up to 8-10% solar cell efficiency where the potential mismatch between the sensitizer and the redox couple is around 0.5 V vs. SCE. If one develops a suitable redox couple that decreases the potential difference between the sensitizer and the redox couple, then the cell efficiency could increase by 30%, i.e., from the present value of 10% up to 13%. Towards this goal, Oskam et al. have employed pseudohalogens in place of the triiodide/iodide redox couples, where the equilibrium potential is 0.43 V more positive than that of the iodide/iodide redox couple.17 Yamada and co-workers have used cobalt tris-phenanthroline complexes as electron relays (based on the CoII/m couple) in dye-sensitized solar cells.95... 

In nearly two decades, challenging structured of phomactins coupled with the interesting biological activity has elicited an impressive amount of synthetic efforts [16-18]. (+)-Phomactin D was first synthesized by Yamada in 1996 [19], and Wulff [20] reported the synthesis of ( )-phomactin B2 in 2007. However, (+)-phomactin A has been the most popular target because of its unique topology. To date, two monumental total syntheses have been accomplished Pattenden s [21] racemic synthesis and Halcomb s [22] asymmetric synthesis in 2002 and 2003, respectively. Both syntheses are beautifully done but also mimicked Yamada s synthesis of D, thereby underscoring the remarkable influence of Yamada s earlier work on the phomactin chemistry. Upon completing their synthesis of ( )-phomactin A, Pattenden [23] completed ( )-phomactin G via a modified route used for A.
