    • NMR and high resolution mass spectra of all the compounds described in this Letter were consistent with the assigned structures. Assignments were further confirmed using 2D NMR and NOE experiments. It should be noted that the yields (represented as Y) reported in this Letter are not optimised. The purity of the compounds was established using various chromatographic techniques. Compounds (3-9), (11), (12), (15), (18-20), (23), (27), (30), and (31) were not crystalline. All other compounds described in the paper were crystalline. Crystals were obtained from DCM-hexane for compounds (1), (2), (21), (22), (25), (26), (28), (29), and (32). The melting points of compounds (1), (2), (21), (22), (25), (26), (28), (29), (32) were 88-90, 96-97, 118-120, 81-82, 95-97, 130-132, 117-118, 96-97, 103-104 °C, respectively.
