Pigments of Fungi. XXII Synthesis of (+/-) Austrocortirubin and Related Tetrahydroanthraquinones

The fungal tetrahydroanthraquinones austrocortirubin (1) and austrocortilutein (3) and their deoxy derivatives (2) and (4), respectively, are synthesized in racemic form from naphthopurpurin (6).

An enantioselective synthesis of (+)-bostrycin leading to a revision of the absolute configuration of its natural antipode

An asymmetric Diels-Alder reaction, involving the protected naphthopurpurin (4) and the D-glucose-derived diene (9a), is used to assemble compound (22), which is transformed by way of compounds (26), (27) and (28) into (+)-bostrycin (3). An X-ray analysis

Bostrycin: Structure Correction and Synthesis

The first synthesis of (+/-)-bostrycin (Scheme I), which is achieved with regio- and stereochemical control, is described.This synthesis, coupled with X-ray crystallographic and other studies, establishes that the structure of bostrycin is 2, which differ
