The squalestatins: Tricyclic 3,4-β-lactone and 3,4-oxetane systems

Squalestatin 3,4-β-lactone-4,5-dimethyl ester (8) was reductively ring-opened to yield squalestatin 3-hydroxymethyl-4,5-dimethyl ester (6) using mild reducing conditions (sodium borohydride). Similarly, squalestatin 3,4-oxetane-4,5-dimethyl ester (10) was

The squalestatins: Synthesis and biological activity of some C3-modified analogues; replacement of a carboxylic acid or methyl ester with an isoelectronic heterocyclic functionality

A series of squalestatins modified at the C3-position with a heterocyclic functionality was prepared and evaluated in vitro as inhibitors of squalene synthase (SQS). Structure-activity relationships for compounds with the 4,6- dimethyloctenoate at C6(S1 a

The squalestatins: C-3 decarboxylation studies and rearrangement to the 6,8-dioxabicyclo [3.2.1]octane ring system

3-Decarboxy squalestatins 3 and 4 were synthesised via photolysis of t-butyl peroxyester 7. Lactol 10 was isolated unexpectedly from both HCl-dioxan cleavage of 8, a by-product of the photolysis, and attempted Barton decarboxylation of 6. In TFA under anh
