Described herein is a synthetic strategy for the total synthesis of (±)-phomoidride D. This highly efficient and stereoselective approach provides rapid assembly of the carbocyclic core by way of a tandem phenolic oxidation/intramolecular Diels-Alde

The enantioselective total synthesis of (–)-stemoamide using Overman/Claisen rearrangement of an allylic 1,2-diol is reported. The enantiopure allylic 1,2-diol was efficiently prepared from naturally occurring dimethyl tartrate. The chirality trans

This article describes the details of two new types of Overman rearrangement from allylic vicinal diols. Starting from identical diols, both bis(imidate)s and cyclic orthoamides were selectively synthesized by simply changing the reaction conditions.

The carbocyclic core of the phomoidrides has been synthesized efficiently and in high yield. Key steps include a phenolic oxidation/intramolecular Diels-Alder sequence, tandem radical cyclization, and a late-stage Wharton fragmentation of a densely f

Human papilloma virus (HPV) is known to be an etiologic agent for benign warts of the skin. Recently, HPV have been detected in malignant skin and mucosal diseases suggesting that HPV infection can induce malignant skin tumors. In the present study,

Trichilemmal tumors can be either benign and malignant skin tumors arising from the outer root sheath of the hair follicle. It remains unknown whether malignant trichilemmal tumors can be differentiated from squamous cell carcinoma (SCC). In order to
