Journal ArticleDOI
Diastereoselective Water Quenching of the 1:2 Michael Adducts of Grignard Reagents with Methyl 2-(Trimethylsilyl)acrylate.
TL;DR: In this paper, a tight chelation working in the 1:2 adduct anions was shown to be responsible for high chemo- and diastereoselectivities of alkyl Grignard reagents with methyl 2-(trimethylsilyl)acrylate.
Journal ArticleDOI
Stereoselectivity of Cycloaddition of N-(Cyanomethyl)- and N-(α-Cyanobenzyl)imines with Olefinic Dipolarophiles.
Journal ArticleDOI
Synthesis of 2-(1-Phosphorylalkyl)- and 2-(1-Alkenyl)furans Through Nitrile Oxide Cycloaddition Route.
TL;DR: In this paper, a new synthetic method of 2-(1-phosphorylalkyl)furans with a variety of substituents on the ring is presented, which is used for alkylation, oxidation with oxygen, or olefination.
Journal ArticleDOI
Novel Ring Contraction of 1,2-Diazocine System. Hydrolysis of 7-Substituted 4-Acetoxy- and 4-Phthalimido-3,8-diphenyl-1,2-diazocines Leading to the Formation of Pyrazoles.
TL;DR: In this paper, a ring contraction of 1,2-diazocine system to pyrazoles via [5.5]bicyclic intermediates has been demonstrated by hydrolysis of 7-substituted 4-acetoxy- and 4-phthalimido-3,8-diphenyl-1,2diazocalines.
