标题:用于α,β-不饱和羧酸与环酮肟酯光诱导脱羧交叉偶联的双镍/钌策略
摘要:在此,开发了一种镍/钌双策略用于 α,β-不饱和羧酸和环酮肟酯之间的光诱导脱羧交叉偶联.反应机理不同于先前的光诱导α,β-不饱和羧酸脱羧.该反应可能通过环丙烷镍中间体进行.通过上述反应构建的 C(Sp 2 )-c(Sp 3 ) 键为在温和的反应条件下获得各种氰基烷基烯烃提供了一种有效的方法,它们是有机和药物化学中具有合成价值的有机骨架.该协议容忍许多关键功能组,并为复杂有机分子的修饰提供了途径.

摘要:The present invention provides an efficient and versatile method for the synthesis and screening of combinatorial libraries of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof. In order to expedite the synthesis of large arrays of compounds possessing these core structures, a general methodology for solid phase synthesis of these derivatives is provided. Arrays of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof useful as peptidomimetics and for the identification of agents having antifungal, antiviral, antimicrobial, anticoagulant, and antiulcer activity, or use in the treatment of inflammation, hypertension, cancer, and other conditions can be prepared by this method.

摘要:Aryl difluoromethyl sulfone adds to aldehydes under phase transfer conditions to give novel substituted alcohols of the general formula n n RCH(OH)CF.sub.2 SO.sub.2 Ar (I) n n wherein R is an aryl, cycloaliphatic, sec- or tert-aliphatic, or heterocyclic group and Ar is an aryl group. The substituted alcohols of formula I are of particular utility as intermediates in the synthesis of a variety of useful end products. For example, the products of formula I may be utilized in desulfonylation reactions, oxidation reactions and fluorination reactions.

标题:Process for preparing conjugates of methyltrithio antitumor agents
发明人：HAMANN PHILIP ROSS; HINMAN LOIS; HOLLANDER IRWIN
权利人:AMERICAN CYANAMID CO
摘要:This invention describes carrier-drug conjugates prepared from disulfide analogs of the calicheamicin family of potent antitumor antibiotics and their derivatives, as well as similar analogs from related antitumor antibiotics such as the esperamicins. The carrier can be an antibody, growth factor, or steroid which targets an undesired population of cells, such as those of a tumor. Whole protein carriers as well as their antigen-recognizing fragments and their chemically or genetically manipulated counterparts are useful for the targeting portion of the conjugates. This invention includes compounds required for the synthesis of these conjugates, appropriate pharmaceutical compositions of the carrier-drug conjugates, and their method of use.
