Despite the rich chemistry of 45 [18], the only method for accessing this compound is the oxidation of the corresponding alcohol derived from 2-methyl-2-propen-l-ol or other sources, which can be obtained through multi-step operations. In contrast to the known methods, 45 can be readily derived from 44 and 50 by a simple one-pot operation. Since the propargylic alcohol 50 a is readily accessed from a ketone or aldehyde, realization of the transformation of 50 to 45 through a one-pot procedure provides a novel method for carbonyl olefmation of ketones or aldehydes.

The double phosphinylation of propargylic alcohols with diphenylphos-phine oxide to form 2,3-bis(diphenylphosphinyl)-1-propenes is catalyzed by a thiolate-bridged diruthenium complex (Scheme 28) [69]. It has been shown that the reaction proceeds via three ruthenium-catalyzed transformations propargylation of the phosphine oxide, alkyne to allene isomerization, and addition of phosphine oxide to the allene structure.

Reduction of propargyl alcohols. 3-Trimethylsilyl-2-propyne-l-ol (1), prepared as shown from propargyl alcohol, is reduced stereospecifically by SMEAH to (E)-3-trimethylsilyl-2-propene-1-ol (2). Reductions of propargyl alcohols with LiAIH4 are less rraws-selective. [Pg.440]

Z)-3-(tri-n-butylstannyl)-2-propen-l-ol, prepared from propargylic alcohol by metal hydride reduction and transmetallation, has been coupled with 1-naphthyl triflate to give (Z)-3-a-naphthyl-2-propen-l-ol with retention of the double bond... [Pg.354]

Like Grignard reagents, " organolithiums can add onto the triple bond of propargylic alcohols. Thus, -butyllithium combines with 3-phenyl-2-propyn-l-ol to give, after hydrolysis, 2-butyl-3-phenyl-2-propen-l-ol almost quantitatively. ... [Pg.82]

The reaction of 1-aryl-2-propynols (propargylic alcohols) with HP(0)Ph2 in the presence of dinuclear ruthenium complexes 30 produces 2,3-bis(diphenyl-phosphino)propene derivatives in high yields (Scheme 44) [45]. [Pg.189]
