Abstract: cf. C.A. 53, 3125i. l-PhCH(OH)Ac (I) boiled with Ac2O and acetylated with AcCl in C5H5N gives the optically active Ac ester, b11 140-1°, 139-40°, [α]20D -211.8 ± 4° (c 4.1, EtOH), -209.7 ± 4° (c 4, EtOH), n20D 1.5064, 1.5063. Benzoylation of I with BzCl in C5H5N yields an optically active Bz ester, m. 49-51°, [α]20D -145.5 ± 4° (c 4.6, EtOH). No isomerization occurs during esterification of I. An optically active Me ether of I, m. 107-9°, [α]20D -145.54° (c 4.6, EtOH) was also prepd.
