The first metal/organo cooperatively catalyzed asymmetric reaction of C-alkynyl N-Boc-protected N,O-acetals with in situ generated oxonium ylides has been developed. This new type of propargylation allows for the efficient synthesis of structurally divers

Acid treatment of α-hydroxy acetals induced 1,2-alkyl, aryl, or alkenyl migration.An alkenyl migration product was utilized as a starting material of methyl L-mycaroside synthesis.
REDUCTION OF NITROALKENES WITH STANNOUS CHLORIDE IN NON-ACIDIC AND NON-AQUEOUS MEDIUM. SYNTHESIS OF α-SUBSTITUTED OXIMES

α, β-Unsaturated nitroalkenes are readily reduced by SnCl2*2H2O in alcoholic media to the α-alkoxy oxime derivatives in high yields.In the presence of ethanethiol, the corresponding α-alkylthio oximes are formed.
A NEW APPROACH TO α-ALKOXY- AND α-ALKYLTHIOKETONES FROM CONJUGATED NITROALKENES
Varma, Rajender S.,Kabalka, George W.
, p. 443 - 450 (2007/10/02)
α-Substituted ketones are obtained in two steps by reduction of the α,β-unsaturated nitroalkenes using SnCl2*2H2O in alcoholic media followed by hydrolysis with levulinic acid.
TRANSFORMATIONS OF 1,1-DIMETHOXY-2-PHENYLCYCLOPROPANE UNDER THE INFLUENCE OF PROTIC ACIDS

, p. 2022 - 2027 (2007/10/02)
Under the influence of protic acids 1,1-dimethoxy-2-phenylcyclopropane undergoes opening of the three-membered ring, the direction of which does not depend on the strength or the nature of the acid but varies with the polarity of the solvent.In acid-solvent systems which exhibit oxidizing characteristics the compound can undergo oxidative cleavage of the cyclopropane ring directly.
