2-Carboxy-3(3-cyclohexen-1-yl)propionic acid, 3-(3-cyclohexen-1-yl)propionic acid and 3-(3-cyclohexen-1-yl)propionyl chloride
were prepared in sequence from ethyl-2-carbethoxy-3-(3-cyclohexen-1-yl)propionate. Cyclization of 3-(3-cyclohexen-1-yl)propionic
acid in polyphosphoric acid resulted in the formation of 4, 5, 6, 7-tetrahydroindanone which was identified by its ultraviolet spectrum
and its physical properties.
7-Bicyclo[3.3.1] nonen-2-one was prepared by a Friedel-Crafts cyclization of 3-(3-cyclohexen-1-yl)-propionyl...
Continuous liquid-liquid two-phase separation is needed in microfluidic devices. Due to the small characteristic lengths of microreactors, phenomena such as mass transport via molecular diffusion occur within seconds. Typically, discrete slugs of an extract are created within microchannels for high specific interfacial area to achieve intensified mass transfer. A challenge...
Cold hardiness and phenology are important adaptive
traits for perennial plant species in temperate climates.
Timing of growth, dormancy, and associated cold acclimation
and deacclimation represents a delicate balance between
maximizing growth under favorable conditions and minimizing
frost damage under unfavorable conditions. Geographic
patterns of genetic variation in adaptive traits,...
