In the case of tiglic aldehyde (224), dithiane 225 was used, and the resulting 1,3-dihydroxyketone 226 was employed in the preparation of the furopyridine antibiotic 2-epi-CJ-16,170 (Scheme 63)355. [Pg.177]

The thermal electrocyclic ring-opening of the cyclobut-2-enol (594 R = H) affords tiglic aldehyde (596 R = H) quantitatively, showing that only the -dienol (595) is formed. This was confirmed by rearrangement of (594 R = D) to (596 R = D) and of (594 R = SiMej) to (595 R = SiMe3), providing a useful synthesis of the aldehydic isoprene synthon. ... [Pg.127]

Polymer-bound diene 25 was subjected to a Diels-Alder reaction with tiglic aldehyde 26 in the presence of tetrame-thylsilane (TMS)-triflate for the construction of the bicyclic core structure (Scheme 16.4). Cycloadduct 27 was obtained as a mixture of four isomers that were formed in a ratio of 67 16 16 1 endolendo lexolexo ) with the desired endo isomer predominating. To improve the stereoselectivity, tiglic aldehyde was converted into the quasi-Ca-symmetric chiral acetal 28 derived with (R,R)-2,4-pentanediol. This chiral dienophile underwent an asymmetric Diels-Alder reaction at -78°C. Removal of the chiral auxiliary from the acetal 29 resulted in the cycloadduct 27 as a mixmre of the four isomers in a ratio of 87 4 9 0.1 endolendo lexolexo ), demonstrating that the stereoselectivity of the main isomer increased from 67% to 87%. ... [Pg.444]
