Stellarator magnetic configurations need to be optimized in order to meet all the required properties of a fusion reactor. In this work, it is shown that a flat-mirror quasi-isodynamic configuration (i.e. a quasi-isodynamic configuration with sufficiently small radial variation of the mirror term) can achieve small radial transport of energy and good confinement of bulk and fast ions even if it is not very close to perfect omnigeneity, and for a wide range of plasma scenarios, including low β and small radial electric field. This opens the door to constructing better stellarator reactors. On the one hand, they would be easier to design, as they would be robust against error fields. On the other hand, they would be easier to operate since, both during startup and steady-state operation, they would require less auxiliary power, and the heat loads on plasma-facing components caused by fast ion losses would be reduced to acceptable levels.

“…In 1996, Kawanami et and the monoacetylated pyrrolidine 85 in excellent enantioselectivities, however, the returned diacetylated pyrrolidine 83 was obtained in significantly lower enantioselectivity. 71 Improved enantioselectivity for diacetate 83 could be obtained with longer reaction times with a small decrease in enantioselectivity for the dihydroxy product.…”

“…Recently, our research group has used a similar approach for the enantioselective preparation of optically active trans -1-benzyloxycarbonyl-3,4-dihydroxypyrrolidines. Optically active diol (3 R ,4 R )- 44 was obtained by CAL-B catalyzed hydrolysis of the diester (±)- trans - 43 , using just 5 equiv of water in 1,4-dioxane at 30 °C (Scheme ) …”
