Scheme 27.—Proposed Mechanism for Photochemical Reaction of (E)-6,7,8-Tri-deoxy-l,2 3,4-di-0-isopropylidene-7-C-nitro-a-D-galacfo-oct-6-enose (75). Scheme 27.—Proposed Mechanism for Photochemical Reaction of (E)-6,7,8-Tri-deoxy-l,2 3,4-di-0-isopropylidene-7-C-nitro-a-D-galacfo-oct-6-enose (75).
An interesting study has been made of the photolysis of a nitro-olefinic sugar.148b Irradiation, at 253.7 nm, of an acetone solution of cis-6,7,8-trideoxy-l,2 3,4-di-0-isopropylidene-7-nitro-o-D-gflIocfo-oct-6-enose (135) gave a complex mixture from which there were isolated the trans isomer 136 and the cis and trans isomers of 6,8-dideoxy-l,2 3,4-di-0-isopropylidene-a-D-gaZacto-oct-5-enos-7-ulose (137 and 138). Insofar as the formation of the two ketones involves the loss of... [Pg.112]
