The classical form of the well-known Reformatsky reaction, introduced for the first time in
1887, 1 consists of the zincinduced formation of b-hydroxyalkanoates from ethyl a …

Enantioselective [2+ 2] cycloaddition of C (1)-ammonium enolates generated catalytically
using the isothiourea HyperBTM with N-alkyl isatins gives spirocyclic β-lactones. In situ ring …

gem-Difluoroolefins with a wide range of substituents are readily synthesized from
commercially available 2, 2, 2-trifluoroethyl p-toluenesulfonate, via a pathway that comprises …

Carbon radicals from allyl O-(trimethylsilyl)-α-bromo-α, α-difluoroacetal can cyclize onto the
olefinic part regiospecifically to give γ-lactols in good yield. The lactols are then converted to …

2-Oxetanon-4-ylcarbinyl radicals undergo facile ring opening with cleavage of the C− O
bond to give 3-butenoxyl radicals which in turn suffer loss of carbon dioxide to provide allyl …

In this paper, the structural and zeta potential properties of 10-hydroxycamptothecin (HCPT)
were investigated by FT-IR and zeta potential analyzer under different pH. The anticancer …

enantioselective formal synthesis of the cyclopentane core of an estrogen receptor β …

In order to investigate the thermal-related properties and thermal stability of 10-
hydroxycamptothecin (10-HCPT) in the solid state, differential scanning calorimetry (DSC) …

Several additional examples of cascade cyclizations of α, β-unsaturated thioesters
proceeding are reported, which proceed via two distinct mechanistic pathways …
