The first total synthesis of 5-(1-hydroxy-1-ethyl)-2-isopropyliden-2H-benzofuran-3-one, is
reported in its racemic and in one of its optically active [(S)-(−)] forms. This heterocycle …

Three new isocoumarins, terrecoumarins A–C (1–3), together with six known isocoumarins
(4–9) were isolated from the fermentation products of the fungus Penicillium oxalicum 0403 …

A straightforward approach toward 6‐bromo‐2‐isopropylidenecoumaranone, a potential
intermediate toward alkaloid TMC 120‐B, pseudodeflectusin, and other natural products …

Abstract Three new lanostane triterpenoids (1-3) along with two new amides fatty
compounds (4-5) were isolated from the ethyl acetate extract of a culture of the endophytic …

In this study, the Aldol condensation between benzofuran-3 (2 H)-ones and ketones or
aldehydes mediated by alumina was developed. This simple protocol facilitated the …

The present invention discloses isoquinolines and 1H-2-Benzopyranes and their use in the
treatment and prevention in epilepsy and other seizures. The present invention further …

The direct oxidative α‐alkoxylation of carbonyl compounds is very important, highly
desirable but relatively rare. A general and convenient approach has been developed to …
