Aminoalcohol lipidoids are prepared by reacting an amine with an epoxide-terminated compound are described. Methods of preparing aminoalcohol lipidoids from commercially available starting materials are also provided. Aminoalcohol lipidoids may be prepared from racemic or stereochemically pure epoxides. Aminoalcohol lipidoids or salts forms thereof are preferably biodegradable and biocompatible and may be used in a variety of drug delivery systems. Given the amino moiety of these aminoalcohol lipidoid compounds, they are particularly suited for the delivery of polynucleotides. Complexes, micelles, liposomes or particles containing the inventive lipidoids and polynucleotide have been prepared. The inventive lipidoids may also be used in preparing microparticles for drug delivery. They are particularly useful in delivering labile agents given their ability to buffer the pH of their surroundings.

This is to provide a process for producing an alkylene oxide adduct which can continuously produce the alkylene oxide adduct with an optional size from a small size to a large size, a temperature and a pressure at the time of the addition reaction can be controlled with high precision, and as a result, the alkylene oxide adduct with high quality having no coloring and narrow molecular weight distribution can be continuously produced, and the above can be accomplished simultaneously, and such an alkylene oxide adduct.
An alkylene oxide adduct was produced by using a microflow reactor having a flow passage with an inner diameter of 0.05 to 3.5 mm, continuously supplying a predetermined amount of alkylene oxide and a predetermined amount of an organic compound having an active hydrogen atom(s) to the flow passage in a liquid state, and these materials were reacted while passing therethrough under the conditions of a temperature of the flow passage of 70 to 200° C. and a pressure of the supply port of the flow passage of 1 to 10 MPa.

The synthesis of terminally functionalized alkanes, which represent potential compounds for formation of self-assembled monolayers, is reported. The alkanes described are substituted at one end with a trichloro- or trialkoxysilyl group suitable for linkage to a hydroxylated silicon surface and at the other hand with a vinyl or amino group for further functionalization.
