A Stereoselective Synthesis of the C10−C31 (BCDEF Ring) Portion of Pinnatoxin A

Organic Letters, 2001
[reaction: see text] An efficient synthesis of the C10-C31 (BCDEF ring) portion of pinnatoxin A has been achieved. The key step is a highly stereoselective construction of the dispiroketal (BCD ring) system employing an intramolecular hetero-Michael reaction of a reversibly formed hemiketal alkoxide through the use of LiOMe.

Morphology, Histology, and Ultrastructure of Human C31 Organ-Cultured Corneas

Cornea, 1995
Our objective was to evaluate corneal structural modifications induced by corneal preservation in a C31 organ culture medium. Twenty-four postmortem human corneas preserved in C31 medium (CRTS, Besançon, France) for 2-21 days and 12 fresh postmortem human corneas were studied and evaluated by means of light microscopy, morphometry, and transmission ...

Conceptual modeling and C31 system design

7th Computers in Aerospace Conference, 1989
An extension to this approach is to provide a "meta-modeling" paradigm that has initially, high level domain specific information and terminology. In theory, as the breadth of the domain is defined, and frameworks for domain structures are incorporated into the representation,' it may be reasonable to approach a domain definition that is both broad and

[Actinophage phi C31 restriction and modification].

Genetika, 1981
Actinophage phi C31 was shown to be insensitive to a number of restriction and modification systems (RM). Phage sensitivity to RM systems of those strains to which phage cannot absorb, may be tested using protoplast transfection. For instance, the absence of phi C13 transfection in Streptomyces griseus Kr15 protoplasts, as compared to efficient ...
