Abstract

A convenient one-pot preparation of substituted hexahydro-4H-chromens via rhodium catalysed tandem hydroformylation starting from 1,5-dienes is described. The multi-step procedure starts with a hydroformylation of one double bond followed by carbonyl ene reaction, a second hydroformylation and enol ether forming cyclisation.

    The lower diastereoselectivity observed in Scheme 8 may be occasioned by the higher temperatures (110°C) for Scheme 8 versus that (90°C) for 38 (Scheme 9).2 The possible transition states for the second cyclization in the formation of 38 have been discussed previously.14 In summary, the relay switch concept provides significant enhancement of the original cyclization–anion capture concept.

    Continued work on the use of dispiroketals in synthesis has led to an improved route to the enantiomers of bi(dihydropyrans) 12 <99JCS(P1)1639>. Hexahydro-4H-chromenes are formed from 1,5-dienes in a one-pot process in which a Rh-complex catalyses sequential hydroformylation, carbonyl ene reaction, a second hydroformylation, cyclisation to a lactol and dehydration <99TL7455>. The oxonium ion generated when dihydropyran is coupled with ethyl glyoxylate in the presence of TiCL4 can be trapped by nucleophiles offering a useful route to 2,3-disubstituted tetrahydropyrans <99TL1083, 4751>.
