A new asymmetric synthesis of chiral 1,4‐dioxanes and other oxa‐heterocycles has been developed by means of organocatalytic enantioselective desymmetrization of oxetanes. This mild process proceeds with exceedingly high efficiency and enantioselectivity to establish the quaternary stereocenters. This method complements the existing, yet limited, strategies for the synthesis of these oxa‐heterocycles

The present invention provides compounds and pharmaceutical compositions for inhibiting N-acylethanolamine acid amidase (NAAA). Inhibition of NAAA is contemplated as a method to sustain the levels of palmitoylethanolamide (PEA) and oleylethanolamide (OEA), two substrates of NAAA, in conditions characterized by reduced concentrations of PEA and OEA. The invention also provides methods for treating inflammatory diseases and pain, and other disorders in which decreased levels of PEA and OEA are associated with the disorder.

An unprecedented enantioselectiveoxetaneopening with chloride provides access to a range of highly functionalized three‐carbon building blocks. The excellent enantiocontrol is enabled not only by a new catalyst, but also by the unusualuse of wetmolecularsieves for the controlledrelease of HCl.
