Tin powder-promoted one-pot synthesis of 3-spiro-fused or 3,3'-disubstituted 2-oxindoles.
A convenient and efficient method for the constructions of 3-spirooxindole derivatives or 3,3'-disubstituted oxindoles has been developed from one-pot reactions of isatins, hydrazides or aromatic amines, 2-(bromomethyl)acrylic ester and tin powder in the presence of a catalytic amount of Brønsted or Lewis acid. The method avoids the use of toxic stannanes and allows easy operation. It is also p...
متن کاملSynthesis of Substituted α-Trifluoromethyl Piperidinic Derivatives.
A comprehensive survey of pathways leading to the generation of α-trifluoromethyl monocyclic piperidinic derivatives is provided (65 references). These compounds have been synthesized either from 6-membered rings e.g., pipecolic acid or lactam derivatives by introduction a trifluoromethyl group, from pyridine or pyridinone derivatives by reduction, and from 5-membered rings e.g., prolinol deriv...
متن کاملSingle enantiomer synthesis of α-(trifluoromethyl)-β-lactam
The first synthesis of α-(trifluoromethyl)-β-lactam ((S)-1) is reported. The route starts from α-(trifluoromethyl)acrylic acid (2). Conjugate addition of α-(p-methoxyphenyl)ethylamine ((S)-3b), generated an addition adduct 4b which was cyclised to β-lactam 5b. Separation of the diastereoisomers by chromatography gave ((αS,3S)-5b). N-Debenzylation afforded the desired α-(trifluoromethyl)-β-lacta...
متن کاملHot water-promoted cyclopropylcarbinyl rearrangement facilitates construction of homoallylic alcohols.
In refluxing 9 : 1 (v/v) H2O-1,4-dioxane and without an additional catalyst, the rearrangements of various types of cyclopropyl carbinols were attempted. It was found that the reactions generally gave homoallylic alcohols in good to very high chemical yields. Rearrangements of bicyclic or tricyclic cyclopropyl carbinols readily gave the desired ring-expanded cyclic homoallylic alcohols which ar...
متن کاملLight promoted synthesis of 1,8-dioxooctahydroxanthenes using sulphated tin oxide as solid support catalyst
In the past few years multi component reactions have captured the attention of synthetic chemists as they provide easy access to diverse complex organic molecules through carbon - carbon and carbon - heteroatom bond formations in tandem manner with simple easy to carry out reaction conditions in short time. 1,8-dioxo-octahydroxanthene is a significant class of oxygen containing...
