Abstract: A process for the production of optically enriched (R)- or (S)-albuterol or (R)- or (S)-albuterol salts by the resolution of a novel ketal derivative 2-(N-t-butylamino)-1-(+2,2-dimethyl-1,2-benzodioxin-6-yl) ethanol, with a chiral tartaric acid derivative.

Abstract: An elongate head and back support with front and rear ends engageable with and between the top of a body supporting the head or back of a person resting on a flat surface; the support includes an elongate upwardly and rearwardly inclined rectangular panel with a forwardly disposed head and back engaging front and a releasable coupling part substantially central of its rear; an elongate T-shaped strut with an elongate inclined post with an upper forward end releasably engaged with said coupling part and a lower rear end adjacent said surface and an elongate transversely extending foot with an upper central portion joined with said rear end, a transversely extending lower edge spaced below said rear end, the lower portion of the foot occurs below the rear end of the post to penetrate and establish anchored engagement in the supporting surface.
