Journal ArticleDOI
A novel synthesis of spirochromenes
TL;DR: In this article, the Mitsunobu coupling of cyclic tertiary ethynyl carbinols followed by the Claisen rearrangement of the ethers obtained provides a short entry to spirochromene systems.
Journal ArticleDOI
Alkylation of Cyclic 1,3-Diketones
TL;DR: A simple procedure for the C-alkylation of cyclic 1,3-diketones has been reported using Triton B as base in aqueous conditions.
Journal ArticleDOI
A facile synthesis of 3-alkylchromanones and chromones
TL;DR: In this article, a simple and high yielding route to 3-alkyl-3-phenyl-sulphonyl-4-chromanones has been achieved from 3-kalkyl, 3-pphenyl, and 3-naphyl, l-4 chromanones.
Journal ArticleDOI
Lithium Tetrafluoborate Catalyzed Ferrier Rearrangement — Facile Synthesis of Alkyl 2,3-Unsaturated Glycopyranosides
TL;DR: In this paper, the treatment of tri-O acetyl-D-galactal with diverse alcohols in the presence of LiBF4 in CH3CN, furnished alkyl 2,3-unsaturated glycopyranosides 3-18 (50-86%).
Journal ArticleDOI
A convenient one-pot synthesis of n-aryl-3-pyrrolines
TL;DR: In this paper, N -propargylanilines, under one-pot homologation conditions, undergo an in situ cyclisation catalysed by Cu(I) to yield 3-pyrrolines in good yield.
