The rapid and regioselective synthesis of a series of 2,6-disubstituted dihydropyranic building-blocks bearing an oxygenated side chain is described. The corresponding 4-iodo tetrahydropyran precursors, easily prepared by Prins cyclization, underwent regioselective elimination in the presence of an In(OAc)3/LiI system to provide the title compounds. The one-pot Prins cyclization-elimination process

A process for preparing a heteroaromatic compound having a heteroaromatic nucleus substituted with one or more ether groups comprising the step of: condensing at least one hydroxy-group of a compound having said heteroaromatic nucleus, said at least one hydroxy group (—OH) being substituted at &agr;- or &bgr;-positions with respect to a heteroatom of said heteroaromatic nucleus, with an alcohol containing one or more primary or secondary alcohol groups, optionally substituted with nitro, amide, ester, halogen, cyano or (hetero)aromatic groups, using the redox couple of a triaryl- or trialkylphosphine and an azodioxo-compound at a temperature between −40° C. and 160° C.
A device, system, and method of controlling pests are disclosed. A pest control device includes a sensor having a sensor cell and a controller. A surface of the sensor cell is coated with an agent that reacts with a targeted biochemical analyte secreted by pests. The controller is coupled to the sensor and is configured to receive sensor data from the sensor cell indicative of a rate of change in sensor mass detected on the surface of the sensor cell, determine whether the rate of change in the sensor mass based on the received sensor data exceeds a predefined threshold rate, and transmit a pest detection alert notification to a server in response to a determination that the rate of change exceeds the predetermined threshold rate.
