The present invention relates to a cationic lipid of formula (I) having one or more biodegradable groups located in a lipidic moiety (e.g., a hydrophobic chain) of the cationic lipid. These cationic lipids may be incorporated into a lipid particle for delivering an active agent, such as a nucleic acid. The invention also relates to lipid particles comprising a neutral lipid, a lipid capable of reducing aggregation, a cationic lipid of the present invention, and optionally, a sterol. The lipid particle may further include a therapeutic agent such as a nucleic acid.
An efficient and commercial phosphorylation process of a complex alcohol, such as secondary and tertiary alcohols, with P4O10 at high temperatures, and a product obtained by the process.

Studies of the bromine-silver carbonate reaction with aliphatic alcohols in which intramoleular δ-H competition is possible are generally quite specific. Loss of tertiary δ- hydrogen occurs preferentially from both tertiary and secondary alfphatic alcohols to yield the most highly substituted cyclic ether. For example, 2,5-dimethyl-2-octanol yields only 2,2,5-trimethyl-5-propyletrahydrofuran as the

The mechanochemical oxidation ofn-pentanol,n-hexanol, andn-octanol with the Pb(OAc)4-MHal system (M=Li, K; Hal=Cl, Br) in the absence of a solvent affords esters. and secondary alcohols with the composition C8H17OH and C9H19OH give ketones.

In one aspect, this invention relates to production of useful fermentation end-products from biomass through simultaneous hydrolysis and fermentation by a microorganism, such as
Clostridium phytofermentans
. The invention also relates to the development of a process for efficient pretreatment and conversion of lignocellulosic biomass to end-products with high conversion efficiency (yield). In another aspect, methods for producing a fermentation end-product by fermenting hexose (C6) and pentose (C5) sugars with a microorganism, such as
Clostridium phytofermentans
are disclosed herein.
