stereoselective macrocyclic ring-closing metathesis reactions that generate Z-enoates as well as (E,Z)- or (Z,E)-dienoates are disclosed. Reactions promoted by 3.0–10 mol % of a Mo-based monoaryloxide pyrrolide complex proceed to completion within 2–6 h at room temperature. The desired macrocycles are formed in 79:21 to >98:2 Z/E selectivity; stereoisomerically pure products can be obtained in 43–75% yield after
A newsynthesis of pteridines possessing a (substituted) (Z)-3-hydroxyprop-1-enyl group at C(6) is based on the acylation of 4-amino-5-nitrosopyrimidines with dienoic acid chlorides, followed by a high-yielding intramolecular hetero-Diels–Alder cycloaddition and cleavage of the NO bond leading to 4. Thermolysis of the resulting pteridines 4 possessing a benzyloxy group at C(4) led to the products 5
