标题 :Convergent synthesis of multiporphyrin light-harvesting rods
发明人：LINDSEY JONATHAN S; LOEWE ROBERT S
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides a convergent method for the synthesis of light harvesting rods. The rods are oligomers of the formula A 1 (A b+1 ) b , wherein b is at least 1, A 1 through A b+1 are covalently coupled rod segments, and each rod segment A 1 through A 1+b comprises a compound of the formula X 1 (X m+1 ) m wherein m is at least 1 and X 1 through X m+1 are covalently coupled porphyrinic macrocycles. Light harvesting arrays and solar cells containing such light harvesting rods are also described, along with intermediates useful in such methods and rods produced by such methods.

标 题 :Spiroannulated nucleosides and process for the preparation thereof
发明人：CHEPURI VENKATA RAMANA; DUSHING MANGESH PANDURANG

摘要:We claim a simple strategy for the synthesis of a collection of C(3′)-spirodihydroisobenzo-furannulated and C(3′)-spirodihydroisobenzo-furannulated nucleosides featuring a [2+2+2]-cyclotrimerization as the key reaction. The cyclotrimerization reactions are facile with the unprotected nucleosides having a diyne unit. When both alkynes of the diyne are terminal, the regioselectivity is poor. However, when one of the terminal alkynes is additionally substituted, the cyclotrimerizations are highly diastereoselective. Since the key bicycloannulation is the final step, this strategy provides flexibility in terms of the alkynes and is thus amenable for the synthesis of a focussed small molecule library.
