摘要:The present invention provides an industrial process for effectively and advantageously preparing optically active 1-substituted amino-2,3-epoxypropanes useful as intermediates for preparing agricultural chemicals and medical products from optically active 1-substituted amino-2,3-propanediols used as raw materials. The present invention also provides useful intermediates. Specifically, an optically active 1-substituted amino-2,3-propanediol (1) is reacted with an orthoacid ester (2) or thionyl chloride (3) to produce a cyclic optically active compound (4), and then a compound (5) containing a halogen atom is prepared by reaction with a ring-opening reaction agent having an ability to introduce a halogen atom X. Finally, an optical active 1-substituted amino-2,3-epoxypropane is prepared by ring-closure reaction in the presence of a base.

标 题 :Bioerodible polymers useful for the controlled release of therapeutic agents
发明人：NG STEVE Y W; HELLER JORGE
权利人:PHARMACEUTICAL DELIVERY SYSTEM
摘要:Bioerodible ortho ester polymers useful for preparing soft form bioerodible pharmaceutical compositions such as ointments, creams, gels and the like are provided. A novel synthetic method for preparing the polymers is provided as well. Synthesis involves a one-step reaction between a monomeric ortho ester and a triol. The pharmaceutical compositions of the invention are useful for the controlled release of therapeutic agents, and may be administered for a variety of purposes, such as for the treatment of deep wounds, including burns, and for the treatment of periodontal disease.

权利人:SAGAMI CHEM RES
摘要:Novel synthesis of dihalovinylcyclopropanecarboxylates, including potent insecticides, are described. The processes begin with the reaction between an alkenol and an orthoester to produce a γ-unsaturated carboxylate, followed by the catalyzed addition of a carbon tetrahalide to the double bond and dehydrohalogenation to produce a cyclopropane derivative.
