| Summary: | No protection is necessary for the synthesis of the muscarine analogue 3R-3-hydroxymuscarine from L-rhamnose; a sole silyl ether protecting group is required for the synthesis of 3S-3-hydroxymuscarine. Efficient construction of the tetrahydrofuran ring can be achieved either by ring contraction of the α-triflate of δ-rhamnonolactone, or by ring opening and closing of the α-triflate of γ-rhamnonolactone. © 1993. |
