We herein describes an HFIP‐mediated [4+ 2]‐cycloaddition reaction from simple and easily
available isatoic anhydrides and cyclopropenones under silver catalysis. This transformation …

Abstract Starting with 3, 5-diphenylcyclohex-2-en-1-one, 3, 5-diphenylcyclohex-2-en-1-
semicarbazone, 1-chloro-3, 5-diphenylcyclohex-2-en-2-carbaldehyde, and 3, 5 …

A convenient synthetic approach to 2-[1-(dialkylamino) alkyl]-4H-3, 1-benzoxazin-4-ones
has been developed. Thus, 1, 1-dimethylethyl 2-isocyanobenzoates, which can be readily …

Novel synthesis of 4H-imidazol-4-one derivative by reaction of (Z)-3-amino-5-(3, 4
dimethoxybenzylidene)-2-phenyl-3, 5-dihydro-4H-imidazol-4-one with derivative of different …

The synthesis of α‐benzamido‐α‐benzyl lactones 23 of various ring size was achieved
either via 'direct amide cyclization'by treatment of 2‐benzamido‐2‐benzyl‐ω‐hydroxy‐N, N …

Indeed, the first synthesis of an α-oxo ketene-(S, S)-acetal was reported in 1910 by Kelber
and co-workers [1]. This compound was prepared by alkylation of β-oxodithioic acid which …

Настоящая работа посвящена изучению различных подходов к синтезу 1, 2, 4-
тризамещенных 5-имидазолонов (23-36) реакцией ненасышенных 5 (4Н)-оксазолонов …
