Sequential Aldol Condensation Catalyzed by Hyperthermophilic 2-Deoxy- d -Ribose-5-Phosphate Aldolase
A new and efficient method has been developed for the synthesis of 4-aryl-7-benzylidene-1,3,4,5,6,7-hexahydro-2H-cyclopenta[d]pyrimidin-2-ones through Biginelli-like reaction of cyclopentanone, with urea/thiourea and aromatic aldehyde employing p-dodecylbenzenesulfonic acid (DBSA) as a recyclable catalyst under solvent-free condition. The recovered catalyst was recycled for further runs. The pr...
We produce Bose-Einstein condensates of 6Li2 molecules in a low power (22W) crossed optical dipole trap. Fermionic Li atoms are collected in a magnetooptical trap from a Zeeman slowed atomic beam, then loaded into the optical dipole trap where they are evaporatively cooled to quantum degeneracy. Our simplified system offers a high degree of flexibility in trapping geometry for studying ultracol...
