Novel formation of dienes with greater steric congestion resulting from the Diels–Alder reaction–desulfonylation sequence of 4-acyl-4H,6H-thieno[3,4-c]furan 5,5-dioxides
4-Acyl-4H,6H-thieno[3,4-c]furan 5,5-dioxides have been prepared and submitted to DielsâAlder reactions to afford dienes with greater steric congestion after desulfonylation.

Three analogs of thyroliberin (I) were prepared. These compounds, N-m-chloroacetylbenzoyl-phenylalanyl-prolineamide (VIa), N-p-chloroacetylbenzoyl-phenylalanyl-prolineamide (VIb) and N-chloroacetyl-alanyl-phenylalanyl-prolineamide (IX), were designed as potential I antagonist affinitylabels. However, no significant antagonist activity was observed. Compounds VIa and IX were found to have weak agonist
