일반 설명
4-Chloro-7-nitrobenzofurazan (NBD-Cl) is a highly sensitive chromogenic and fluorogenic reagent. It is reported to react spontaneously with trans-1-methoxy-3-(trimethylsilyloxy)-1,3-butadiene (Danishefsky′s diene), to afford regioselectively the silyl enol ether, via normal electron-demand Diels-Alder (NEDDA) reaction. A study of the molecular structure, vibrational spectra and NBO (Natural Bond Orbital) analysis of NBD–Cl has been undertaken. Its utility as a pre-column derivatization agent has been examined.

Lipase B from Candida antarctica (CAL-B) has been site-directedly modified by the introduction of a trans,trans-hexadiene moiety onto lipase molecules, identified by MALDI-TOF. This modification on CAL-B permitted its immobilization on Q-Sepharose supports in excellent yields (>95%) when native lipase
