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:Facile synthesis of 1,9-diacyldipyrromethanes
发明人：LINDSEY JONATHAN S; TAMARU SHUN-ICHI; YU LIANHE
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides a method of making a metal complex. The method comprises the steps of: (a) acylating a dipyrromethane or a 1-monoacyldipyrromethane to form a mixed reaction product comprising a 1,9-diacyidipyrromethane; (b) combining the reaction product with a compound of the formula R 2 MX 2 in the presence of a base, where R is alkyl or aryl, M is Sn, Si, Ge, or Pb (preferably Sn), and X is halo, OAc, acac, or OTf, to form a product comprising a metal complex of the formula DMR 2 in the mixed reaction product, wherein D is a 1,9-diacyldipyrromethane; and then (c) separating the metal complex from the mixed reaction product. The method may be utilized for the convenient synthesis and separation of 1,9-diacyldipyrromethanes. Metal complex intermediates useful in such methods are also described.

权利人:NUTRASWEET CO
摘要:This invention relates to the chemical synthesis of N-[N-(3,3-dimethylbutyl)-L-α-aspartyl]-L-phenylalanine 1-methyl ester using peptide coupling methods. The coupling reaction is conducted by condensation of an activated derivative of novel N-neohexyl-L-aspartic acid with L-phenylalanine or L-phenylalanine methyl ester or by enzymatic coupling of N-neohexyl-L-aspartic acid with L-phenylalanine or L-phenylalanine methyl ester. This invention also relates to novel N-(3,3-dimethylbutyl)-L-aspartic acid, derivatives thereof and the preparation thereof. The activated derivative of N-neohexyl-L-aspartic acid may be an anhydride, mixed anhydride, active ester or an intermediate activated derivative thereof.
