Some efforts directed towards synthesis of the C-1 to C-18 fragment of natural antibiotic pamamycins 607 and 621A are disclosed. The nine stereogenic centers in the fragment were installed using a chiral auxiliary-induced asymmetric aldol reaction, a chir
Asymmetric epoxide cyclisation route to the F-pyran fragment of the altohyrtins and key aldol studies

The evolution of an asymmetric synthesis of a differentially protected F-pyran ring of the altohyrtins is described, which relies on a key intramolecular cyclisation of a C43 hydroxyl group onto a C38-C39 epoxide. The C38-C39 epoxide stereochemistry was achieved through optimisation of substrate control. Key aldol studies towards coupling the F-pyran ring with an E-pyran ring precursor was investigated, but unsuccessful. (C) 2000 Elsevier Science Ltd.
