Abstract: Novel aldehyde-functionalized polysaccharide compositions are described that are more stable in aqueous solution than oxidized polysaccharides or other types of polysaccharides containing pendant aldehyde groups. The aldehyde-functionalized polysaccharides may be reacted with various amine-containing polymers to form hydrogel tissue adhesives and sealants that may be useful for medical applications such as wound closure, supplementing or replacing sutures or staples in internal surgical procedures such as intestinal anastomosis and vascular anastomosis, tissue repair, preventing leakage of fluids such as blood, bile, gastrointestinal fluid and cerebrospinal fluid, ophthalmic procedures, drug delivery, and preventing post-surgical adhesions.

Abstract: This invention relates to dibenzothiopyran compounds. This invention also relates to layers and devices including at least one of these compounds.

Abstract: It was found that glycidyloxystyrenes, including glycidyloxystyrene and substituted glycidyloxystyrene, can be synthesized from hydroxycinnamic acid or substituted hydroxycinnamic acids in a one-pot, two-step process. The substrate can be thermally decarboxylated and then without purification, reacted in the presence of a halomethyl-oxirane and a base. The resulting product can be polymerized or coppolymerized to a fully substituted product.

Abstract: Tyrosine was converted to p-hydroxystyrene in a two-step reaction without purification of individual intermediates. Conditions were determined for bromination of tyrosine in which reactive intermediates were formed. The mixture of these intermediates was used directly in a second step reaction to produce p-hydroxystyrene. The p-hydroxystyrene was further acetylated to produce p-acetoxystyrene in the second step reaction vessel.

Abstract: Three different reaction steps were combined to provide methods for preparing p-hydroxystyrene and p-hydroxycinnamic acid monomers from tyrosine. The three steps include reductive alkylation of tyrosine, followed by oxidation to the N-oxide, and thermal Cope elimination. During Cope elimination, either p-hydroxycinnamic acid or p-hydroxystyrene was produced depending on the absence or presence of base, respectively. Additionally, p-acetoxystyrene may be prepared by reacting the prepared p-hydroxystyrene either directly or after isolation with an acetylating agent.
