Many natural products of biological interest contain [6,5]- and [6,6]-spiroketal moieties that can adopt various configurations, benefiting or not from anomeric conformation stabilizing effects. The spiroketal fragments are often important for the bi

The development of efficient routes to multi-gram quantities of chiral synthons is a key issue in the total synthesis of natural products and analogues. The conformationally defined and rigid 8-oxabicyclo[3.2.1]oct-6-en-3-one template is an appealing

Starting from the readily available meso-methylenedi(8-oxa-3-oxobicyclo[3.2.1]hept-6-en-1-yl) (1), meso-1,1'-methylidene [(4R,4'S,6R,6'S)-4,6-dioxycyclohept-1-en-1-yl]tetrasilylethers (7, 8) were obtained and transformed into all-syn 1,3,5,11,13,15-h

A sequence of highly diastereoselective functionalizations allowed transformation of a meso-methylenebis(cyclohept-3-ene-1,6-diyl diester) into an advanced precursor of the AB spiroketal of spongistatins. This route illustrates the potential of this

A solid-phase synthesis of new N-substituted valienamines has been developed and new synthesis of (±)-conduramine F-1, (−)-conduramine F-1, and (+)- ent -conduramine F-1 is presented, together with the preparation of N-benzylated conduramines F-1.

A range of new tetra- and pentahydroxylated seven-membered iminoalditols has been efficiently synthesized from epoxyazepane precursors via nucleophilic opening with hydride or oxygenated species and subsequent hydrogenolysis. One tetrahydroxylated az
