Combined holographic-mechanical optical tweezers: construction, optimization, and calibration.

30 Jul 2009 A spatial light modulator (SLM) and a pair of galvanometer-mounted mirrors (GMM) were combined into an optical tweezers setup. This provides great flexibility as the SLM creates an array of traps, which can be moved smoothly and quickly with the ... Read more...

Enantioselective total synthesis of all of the known chiral cleroindicins (C-F): clarification among optical rotations and assignments.

3 Jun 2009 Enantioselective syntheses of all of the named chiral members of the cleroindicin family (C-F) are reported. This effort demonstrates the synthetic utility of a 2,4-dihydroxybenzaldehyde as a starting material for natural product synthesis through ... Read more...

Resolution/deracemization of chiral alpha-amino acids using resolving reagents with flexible stereogenic centers.

Jun 2009 This work has demonstrated that a previously unexplored approach to separation of enantiomers via formation of diastereomeric derivatives with three stereogenic centers has obvious practical potential and deserves further systematic study. The ... Read more...
