520 | __ | |aThe present study is focussed on the stereoselective total synthesis of some naturally occurring lactones, semiplenamides and isolation of bioactive natural products. newline6-Substituted-5,6-dihydro-2H-pyran-2-one is an important structural subunit in many biologically promising natural products. newline(6 S)-5,6-Dihydro-6-[(2 R)-2-hydroxy-6-phenylhexyl]-2H-pyran-2-one and dodoneine are amongst them that attracted our focus for newlinesynthesis due to their interesting biological activities and structural similarities. The pyranone unit of both molecules was brought newlinethrough a common intermediate with varying asymmetric centres. These lactone intermediates, ( S) - and ( R)-2-(6-oxo-3, 6-dihydro-2H-pyran-2-yl) acetaldehydes have further been accomplished from 1,3-newlinepropanediol employing Maruoka asymmetric allylation and ring closing metathesis reaction. These intermediates were converted into desired natural products (6 S)-5,6-Dihydro-6-[(2 R)-2-hydroxy-6-phenylhexyl]-2H-pyran-2-one and dodoneine |
