Reduction McFadyen-Stevens

Acyl sulfonylhydrazides (117) are cleaved with base to give aldehydes. This is known as the McFadyen-Stevens reduction and is applicable only to aromatic aldehydes or aliphatic aldehydes with no a hydrogen. " RCON=NH (see 10-87) has been proposed as an intermediate in this reaction. " °... [Pg.534]

The hydrazide of 2,2-diphenyl-3-hydroxypropanoic acid was reduced with lithium aluminum hydride in 7V-ethylmorpholine at 100° to 3-amino-2,2-di-phenylpropanol in 72.5% yield [1145], Much more useful is reduction of N-arenesulfonylhydrazides of acids to aldehydes McFadyen-Stevens reduction) [284, 285] based on an alkali-catalyzed thermal decomposition according to Scheme 174. [Pg.172]
