Efficient synthesis of ningalin C

(Matrix presented) A concise and efficient synthesis of the permethyl derivative of the marine alkaloid ningalin C (2) has been accomplished. The key step involves the formation of a pyrrolinone fron an aminoquinone in one pot. An efficient route for the

From phenylacetylphenylacetic acids and 1-benzylisoquinolines to 6,11-dihydrobenzo[b]naphtho[2,3-d]furan-6,11-diones, 6H-dibenzo[c,h]chroman-6-ones and 7,12-dihydro-5H-dibenzo[c,g]chroman-5,7,12-triones via 2-phenyl-3-hydroxy-1,4-dihydro-1,4-naphthalenediones or 2-phenyl-1-naphthols

We describe the synthesis of 6,11-dihydrobenzo[b]naphtho[2,3-d]furane-6,11-diones, 6H-Dibenzo[c,h]chroman-6-ones and 7,12-dihydro-5H-dibenzo[c,g]chroman-5,7,12-triones from 2-(2'-phenyl)-3-hydroxy-1,4-dihydro-1,4-naphthalenediones or 2-phenyl-1-naphthols obtained from 2-(2'-bromophenylacetyl)-phenylacetic acids or 1-benzylisoquinolines.

Reaction of 1-(3,4-Dimethoxybenzylidene)-6,7-dimethoxyisochroman-3-one with Lithium Aluminium Hydride: Formation of 1-(3,4-Dimethoxybenzylidene)-6,7-dimethoxyisochroman

Evidence is presented to indicate that the reductive reaction of the isochromanone derivative 1 by means of lithium aluminium hydride (LAH), yielded the isochroman 2 together with small amounts of naphthalene derivatives.All new compounds have been identi
