Abstract

1355668 #-Acetylenic alcohols HEXACHIMIE 7 July 1971 [9 July 1970] 54624/73 Divided out of 1355667 Heading C2C Novel compounds I in which R is H, COOH or (1-6 C alkoxy)- carbonyl; R 1 is H or 1-6 C alkyl and R 2 is 1-6 C alkyl, phenyl-1-6 C alkyl, methoxyphenyl-1-6 C alkyl, or methylenedioxyphenyl- 1-6 C alkyl; with the proviso that R 2 is not propyl when R is H or COOH and R 1 is H are prepared by reaction of a ketone R 1 COR 2 with a propargyl metal halide HC#C-CH 2 -(2/mM)X (X is halo, M is Mg or Al and m is the valency of M) to give I (R is H), followed, where desired, by reaction with an alkyl magnesium halide and then carbon dioxide; and optionally esterification of the compound I (R is COOH) produced.
