Compounds 1-methylisatin (3a, 5-bromo-1-methylisatin (3b, 1-ethylisatin (3c, 5-bromo-1-ethylisatin (3d, 1-benzylisatin (3e) and 1-benzyl-5-bromoisatin (3f) were prepared from alkyl benzensolfonates and the potassium isatin or potassium 5-bromoisatin by known methods.29 Melting points were measured on an Electrothermal 9100 apparatus and are uncorrected. Elemental analyses for C, H and N were performed using a Heraeus CHN-O-Rapid analyzer. IR spectra were measured on a Perkin-Elmer 783 infrared spectrophotometer. 1H, 13C and 31P NMR spectra were measured using a Bruker DRX-250 Avance spectrometer at 500, 125.7 and 202.5 MHz, respectively. Mass spectra were recorded on a Shimadzu GCMS-QP5050 mass spectrometer operating at an ionization potential of 70 eV. Preparation of 1-(morpholinomethyl)isatin (3g, A slurry consisting of the isatin (5 mmol, THF (5 mL) and formalin 2 mL, 37, was made. T

General procedure for the synthesis of diisopropyl-2′,2′, 2′-triphenyl-2-oxospiro[1-methylindole-3,5′-(2′, 5′-dihydro-1′,2′-λ5-oxaphosphole, 3′, 4′-dicarboxylate(4a, To a magnetically stirred solution of N-methylisatin (2 mmol) and PPh3 (2 mmol) in CH 2Cl2 (3 mL) was added dropwise, DIAD (2 mmol) at r.t. over 10 min. After 5 h the crude reaction mixture was diluted with CH 2Cl2 and passed through a short plug of silica gel. The solvent was removed under reduced pressure and the residue was purified by silica gel column chromatography to give a white powder; mp 177-178°C; IR (KBr, 1720 (N-C=O) 1735, 1740 (2 CO2i-Pr, 1660 (C=C, 1610 (C=Carom, 1430, 1107, 1009 (P-Ph, 1010 (P-O) cm-1; 1H NMR (500 MHz, CDCl3, δ, 0.72 d, J, 6.2 Hz, 3 H, CHMe2
