Abstract

(10 mmd 1 50'c/83 hr compound 3b7 shows no carbonyl absorption in its IR and a doublet (J= 4.0 Hz, 1H) at 6 4.53 in its HI NMR. The doublet signal assigned to the C-9a proton of 3b was decoupled to a singlet by irradiating multiplet signals near 6 2.4, which may be assigned to a proton on C-4a. The small coupling constant (J4a-9a= 4.0 Hz) may be attributed to the existence of cis-fused tetrahydropyran ring8
