Abstract
Experimental Section General Remarks. H NMR and C NMR spectra were recorded for a solution in CDCl3 with tetramethylsilane (TMS) as internal standard and J-values are in Hz. Mass spectra were recorded with a HP-5989 instrument. Organic solvents used were dried by standard methods when necessary. Commercially obtained reagents were used without further purification. All reactions were monitored by TLC with Huanghai GF254 silica gel coated plates. Flash column chromatography was carried out using silica gel at increased pressure. Reaction experiments were performed under argon atmosphere using standard Schlenk techniques.
