2 at -78 °C, then warming to 0 °C (over 2h). The mixture was then re-cooled to -78 °C and (1a) was added (over 2h via syringe pump) and the mixture was then warmed to r.t. over 4h, after which time McOH(D) was added. Interestingly, when both "normal" and "aged" reactions were monitored by TLC, (8) and (9) were the major components observed. However, when these reactions were subsequently quenched with MeOD, (6) and (7) isolated contained no incorporation of deuterium at C(3). This suggests (i) that (9) is not involved in the pathway leading to (6/7) (although the species present in solution appears to break down to (9) on TLC), (ii) the "aged" reagent is quite distinct to that produced under "normal" conditions and (iii) that two discreet animation pathways are available. We have been unsuccessful in converting (9) to (6/7) using MeOH and PyHTs (pyridinium tosylate) but thermolysis (PhMe, PyHTs, 100°C) of (7) gave (9) (20%) together with (6) (30%) and recovered (7) (15%).
