摘要：

Preparation and stereochemical behavior of new examples of isolable rotamers are described. Reaction of hydroxylactone 2 with isocyanates 3 - 11 gave the corresponding 12 - 20 in good yields. Among them, ortho di-substituted ones gave isolable rotamers. The behavior of ortho mono-substituted derivatives is also discussed.
