  • Patent number: 8461384
    Abstract: The present invention is directed to processes for the synthesis of morphinans. In particular, a process for coupling a carboxylic acid compound with an amine compound to form an amide product that can then be isolated or the crude amide product can be cyclized to form a 3,4-dihydroisoquinoline. In one embodiment, the carboxylic acid contains a phenol moiety protected with a labile protecting group. The protected phenol reduces reaction times, simplifies work-up of the product, and reduces the amount of cyclizing agent, POCl3 that is necessary to form the 3,4-dihydroisoquinoline.

  • Patent number: 4895970
    Abstract: Poly(alkylene carbonate) monoahls and polyahls useful as non-ionic surfactants having a poly(alkylene carbonate) backbone are prepared by reacting an oligomeric poly(alkylene carbonate) with a compound having mono- or difunctional active hydrogen moieties, such as alcohols, carboxylic acids, mercaptans, amides, primary or secondary amines, or substituted phenols, in the presence of a catalyst under transesterification conditions. Novel modified poly(alkylene carbonate)monoahls and polyahls are prepared by reactions of mercaptans with poly(alkylene carbonate)polyahls.
