    • All the mixtures in entries 1-3, Table 1, were mixed to give an average 9a:9b = 37:63 mixture and 85% yield. This on separation by preparative thin layer chromatography (PTLC) gave 9a in 30% yield and 9b in 51% yield from 19. These yields were taken into account while calculating the overall yield.
