Abstract
Activation of a hydroxyl group towards nucleophilic substitution via reaction with methanesulfonyl chloride or PPh3-CBr4 system is a commonly used pathway to various functional derivatives. The reactions of (5R(S),6R(S))-1-X-6-(hydroxymethyl)-2,2-dimethyl- 1-azaspiro[4.4]nonanes 1a–d (X = O·; H; OBn, OBz) with MsCl/NR3 or PPh3-CBr4 were studied. Depending on substituent X, the reaction afforded hexahydro-1H,6H-cyclopenta[c]pyrrolo[1,2-b]isoxazole (2) (for X = O), a mixture of 2 and octahydrocyclopenta[c]azepines (4–6) (for X = OBn, OBz), or perhydro-cyclopenta[2,3]azeto[1,2-a]pyrrol (3) (for X = H) derivatives. Alkylation of the latter with MeI with subsequent Hofmann elimination afforded 2,3,3-trimethyl-1,2,3,4,5,7,8,8a-octahydrocyclopenta[c]azepine with 56% yield.

Abstract
Four amino acid dicarboxylic amphiphiles which contain cysteine or homocysteine were synthesized. Each forms synthetic bilayer membranes upon hydration. Extensive sonication above the lipid phase transition temperature, 61 to 82 degrees C, produced 1000 A diameter vesicles. Treatment of the vesicles with water-soluble carbodiimides during and after sonication induced oligopeptide formation at the vesicle surface with retention of vesicle size and shape. Size exclusion chromatography indicates the products are predominantly di- to decapeptides. The permeability characteristics of the amino acid and peptide vesicles to [3H]glucose and 6-carboxyfluorescein are reported. The amino acid vesicles are among the least permeable nonpolymerized bilayer vesicles described in the literature to date. Formation of the peptide vesicles increases the membrane permeability, whereas in other polymerizable lipid vesicles the permeability decreases upon polymerization. The amino acid vesicles can be immobilized on Sephadex beads by reaction with carbodiimide. The impermeability, biodegradability, and ease of immobilization make this class of vesicles attractive materials for the encapsulation of reagents.

Abstract
A convenient method for transforming 3-acyl-sn-glycerols into 1-acyl-2,3-diacyl'-sn-glycerols, antipodes of 1,2-diacyl'=3-acyl-sn-glycerols, of relatively high optical purity, via the 1,2-dimesyl-3-acyl-sn-glycerols has been worked out. ORD and CD curves of optically active triglycerides and also some mono- and diglycerides have been studied in detail. The curo 200 nm or below. A Cotton effect from the n yeilds ets* transtition of the ester chromophore was observed at 215-220 nm, which was negative for triglyceritical rotations could be observed in triglycerides with very small differences in chain length, such as 1,2-dilauroyl-3-myristoyl-sn-glycerol.
